Capital: A Critique of Political Economy (German: Das Kapital. Kritik der politischen Ökonomie), also known as Das Kapital (German: [das kapiˈtaːl]), is a foundational text in Marxist theory by Karl Marx. His magnum opus, the work is a critical analysis of political economy, meant to reveal the economic patterns underpinning the capitalist mode of production. Capital is divided into three volumes, of which only the first was published during Marx's lifetime, in 1867; the others were completed from his manuscripts and published by his collaborator Friedrich Engels in 1885 and 1894.
The central argument of Capital is that the motivating force of capitalism is in the exploitation of labour, whose unpaid work is the ultimate source of surplus value and profit. Beginning with an analysis of the commodity, Marx argues that the capitalist mode of production is a historically specific system where social relations are mediated by commodity exchange. He posits a labour theory of value, contending that the economic value of a commodity is determined by the socially necessary labour time required for its production. Under this system, the worker's capacity to labour (their labour power) is sold as a commodity, but its use-value—the ability to create new value—is greater than its exchange-value (the wage), allowing the capitalist to extract surplus value. This process drives capital accumulation, which in turn fosters technological change, the creation of a reserve army of labour, and a long-term tendency of the rate of profit to fall, leading to economic crises and intensifying class conflict.
In developing his critique, Marx synthesised and critiqued three main intellectual traditions: the classical political economy of thinkers like Adam Smith and David Ricardo, the German idealist philosophy of Georg Wilhelm Friedrich Hegel, and French socialist thought. His dialectical method aimed to uncover the internal contradictions and historical transience of capitalism. A key theme is commodity fetishism, the process by which the social relations of production are obscured and appear as objective, natural relations between things. Volume I focuses on the production process, Volume II on the circulation of capital, and Volume III on the process as a whole, examining the distribution of surplus value into profit, interest, and rent.
Capital is one of the most influential works of social science ever written. Its analysis has been foundational to the international labour movement, socialist and communist political parties, and a wide range of academic disciplines, including sociology, political science, and philosophy. It remains central to Marxian economics and has been highly influential in Western Marxism, critical theory, and cultural studies. The work has been subject to extensive debate and criticism since its publication, particularly concerning its labour theory of value, its predictions about the future of capitalism, and its association with 20th-century communist states.
Background and influences
Karl Marx's Capital emerged from his lifelong project of developing a comprehensive "critique of political economy". His work was a synthesis and critical engagement with three major intellectual and political traditions: classical political economy, German critical philosophy, and utopian socialism.
Marx meticulously studied classical political economists from the seventeenth to the mid-nineteenth century. This included British thinkers like William Petty, John Locke, Thomas Hobbes, David Hume, James Steuart, Adam Smith, Thomas Malthus, and David Ricardo. He also engaged with the French tradition of Physiocrats like François Quesnay and Anne Robert Jacques Turgot, and later economists such as Jean Charles Léonard de Sismondi and Jean-Baptiste Say. His extensive notes on these thinkers, published as Theories of Surplus Value, demonstrate his method of deconstructing their arguments, accepting certain insights while identifying gaps and contradictions to transform their theories. His critique aimed not just at specific theories but at the categorical presuppositions of the entire field, challenging the way political economy posed its questions and what it accepted as self-evident. Marx distinguished his approach from classical political economy specifically regarding the treatment of labour; whereas Ricardo viewed labour transhistorically as the source of wealth, Marx analysed labour as a historically specific social form ("abstract labour") unique to capitalism.
Philosophical reflection, originating with Greek thought (Marx wrote his dissertation on Epicurus and was familiar with Aristotle), formed another crucial foundation. He was thoroughly trained in the German philosophical tradition, particularly the works of Baruch Spinoza, Gottfried Wilhelm Leibniz, Immanuel Kant, and, most significantly, Georg Wilhelm Friedrich Hegel. The critical climate generated by the Young Hegelians in the 1830s and 1840s, and Marx's engagement with thinkers like Ludwig Feuerbach, profoundly influenced his early development. From Hegel, Marx adopted and transformed the dialectic, a method for understanding processes of motion, change, and contradiction. Influenced by Feuerbach's materialism, he broke with Hegelian idealism, arguing that social consciousness is determined by material conditions, not the other way around. This synthesis of dialectics with a materialist understanding of history became a cornerstone of his method. Some interpretations suggest that Marx's mature critique of Hegel was not a simple materialist inversion, but an attempt to show that the "rational core" of Hegel's idealist dialectic—a self-moving "Subject" that grounds itself—is actually the alienated social structure of capital itself.
The third major influence was utopian socialism, primarily French in Marx's time, though with English precursors like Thomas More and Robert Owen. Thinkers such as Henri de Saint-Simon, Charles Fourier, and Pierre-Joseph Proudhon, as well as figures like Étienne Cabet and Louis Auguste Blanqui, contributed to a vibrant utopian discourse in the 1830s and 1840s. Marx was familiar with this tradition, particularly during his time in Paris in 1843–1844. While he sought to distance himself from what he saw as the shallow utopianism that failed to provide a practical path to a new society, he often proceeded in his arguments by way of a critical negation of their ideas, particularly those of Fourier and Proudhon. His aim was to convert what he considered a rather superficial utopian socialism into a "scientific socialism", by interrogating classical political economy with the tools of German critical philosophy, all applied to illuminate the French utopian impulse.
Marx's aims and method
Marx's fundamental aim in Capital was to "lay bare the economic law of motion of modern society". He sought to uncover the specific historical laws governing the origins, development, and decline of the capitalist mode of production, rather than searching for eternal or universal economic laws applicable to all societies. For Marx, an essential thesis of Capital is that such universal laws do not exist; each specific social form of economic organisation has its own specific economic laws. This was not merely an academic exercise; his work was driven by a commitment to critical theory and the revolutionary transformation of society. He aimed to provide a "rock-like foundation of scientific truth" for the workers' movement by revealing the inherent contradictions and exploitative nature of capitalism. In this vein, some interpretations read Capital not merely as a scientific analysis but as a political weapon designed to arm workers by revealing the dynamics of class struggle from a working-class perspective, helping to win them over to the ideas of internationalism and labour activism.
Marx's method of presentation in Capital, as he explained in the postface to the second German edition, differed from his method of inquiry. The inquiry involved appropriating the material in detail, analysing its different forms of development, and tracking down their inner connections. Only after this work was done could the "real movement be appropriately presented". This process corresponds to what he termed the "descending path", moving from the confused appearances of economic life to uncover the essence at its deepest layer. The presentation, conversely, follows an "ascending path", starting from the most abstract essence to progressively clarify phenomenal forms and arrive back at the concrete totality. Consequently, Capital begins by laying out foundational concepts—such as the commodity, value, and money—in a somewhat a priori fashion in the opening chapters, making the initial reading particularly arduous. Marx's argument unfolds not in a linear, brick-by-brick manner, but more like an "onion", starting from surface appearances, moving to a conceptual core, and then growing outward again, with concepts becoming richer and more meaningful as the analysis progresses.
A key aspect of Marx's method is the use of abstraction. Recognising that social science cannot conduct controlled experiments in a laboratory, Marx employed the "power of abstraction" to isolate and analyse the fundamental dynamics of capitalism. His analysis focuses on the capitalist mode of production in its "pure" form, often abstracting from historical contingencies or specific empirical variations to reveal underlying structures and tendencies. His method makes use of several distinctive "thought figures", such as the analysis of phenomena as twofold or contradictory; "eversion", where elements switch their hierarchical position; and the processes of abstraction and personification through which social relations take shape.
The dialectical method is central to Marx's approach, though he never wrote a separate treatise on it. Derived from Hegel but "turned right side up again" in a materialist framework, Marx's dialectic views economic phenomena not in isolation but in their inner connection as an "integrated totality, structured around, and by, a basic predominant mode of production". It aims to understand "every historically developed form as being in a fluid state, in motion", grasping the "transient aspect" of society by uncovering the internal contradictions that drive its development and eventual disappearance. A central dialectical theme is the distinction between a phenomenon's essence (or content) and its appearance (or form), such as the way the wage conceals the underlying exploitation of labour. Rather than a closed system of thesis, antithesis, and synthesis, Marx's dialectic is an "expansionary logic", where contradictions are internalised and lead to further development of the argument, revealing a "perpetual expansion of the contradictions". The dialectic in Capital is also interpreted by some as a critique of the "transhistorical" view of history; rather than positing a universal logic of history, Marx identifies a specific directional dynamic inherent only to the capitalist social formation, driven by its internal contradictions.
The starting point of Capital with the commodity appears somewhat arbitrary to many readers. Marx had struggled for decades with where to begin his critique. His "method of descent"—proceeding from immediate reality to deeper, fundamental concepts—led him to the commodity as the elementary form of wealth in capitalist societies, containing in embryonic form all the system's inner contradictions. From this starting point, which is itself a theoretical construct derived from abstraction rather than a simple empirical given, Marx unfolds his analysis, examining the dual character of the commodity (use-value and exchange-value), which leads to the concept of value, and then to money as the necessary form of appearance of value. This progression through dualities and their (often contradictory) unities is characteristic of his dialectical presentation. The method is one of immanent critique, analysing the categories of the society "in their own terms" to reveal their internal inconsistencies and the possibility of their historical negation.
Marx's critique of political economy is not simply a refutation of previous theories but a critique of the very categories and presuppositions of bourgeois economic thought. He challenges the "naturalisation" and "reification" of social relations, whereby historically specific capitalist relations are presented as eternal and natural properties of things. A central example is the fetishism of commodities, where the social relations between producers appear as relations between things (the products of their labour), obscuring the underlying social reality. This "enchanted, distorted and upside-down world" is not a subjective illusion but an objective appearance that arises from the specific social form of labour in a commodity-producing society. Marx aims to penetrate this "religion of everyday life" that underpins both everyday consciousness and the categories of political economy.
Writing process
The writing of Capital was a long and arduous process, spanning several decades. Marx began intensive economic studies in the 1840s, and after being interrupted by the revolutions of 1848 and subsequent exile, resumed his systematic research in London in the early 1850s. His Economic and Philosophic Manuscripts of 1844 represent an early, rough draft of ideas that would eventually mature into Capital. According to some scholars, Capital can be seen as the logical culmination of the theory of alienation (or dehumanisation) that Marx first explored in these early manuscripts. The precise nature of Marx's break from Hegelian philosophy and the scientific status of his new method would become a central point of contention among 20th-century Marxists, exemplified by Louis Althusser's influential theory of an "epistemological break" separating the mature Marx of Capital from his earlier, more Hegelian-influenced works.
Throughout the 1850s and 1860s, Marx filled numerous notebooks with research, excerpts from economic texts, and his own developing theories. The Grundrisse, a lengthy manuscript written in 1857–1858, represents a significant milestone in the development of Capital, containing extensive discussions on alienation, dialectics, and the theory of value. In contrast to the polished and perfected final version, the Grundrisse reveals the "chisel marks" of Marx's method, with a terminological ambiguity that would later be resolved; for example, "labour" is often used generically to refer to both the worker's capacity to labour and the activity of labour itself, a distinction later clarified with the precise concept of "labour-power". A preliminary version, A Contribution to the Critique of Political Economy, was published in 1859 but covered only a fraction of Marx's planned work and received little attention. Marx continued to revise and expand his manuscript, driven by new research and his engagement with events like the American Civil War and the rise of the International Working Men's Association (First International), of which he became a leading figure. The intellectual project of writing Capital and the political work of the International were "intertwined"; Marx saw the book as a vital tool for the workers' movement and was, in turn, influenced by the practical struggles of the workers he engaged with.
Marx's perfectionism and his tendency to get sidetracked by polemics and contemporary political events significantly delayed the book's completion. He often complained of ill health, particularly liver problems and carbuncles, which he attributed to the stress of his work and dire financial circumstances. His friend and collaborator Friedrich Engels provided crucial financial and intellectual support throughout this period, frequently urging Marx to complete the work. In February 1867, shortly before delivering the first volume to the printers, Marx urged Engels to read Honoré de Balzac's The Unknown Masterpiece. He saw a parallel between the story's protagonist, a painter who endlessly reworks his masterpiece to the point where nothing remains, and his own protracted struggle with Capital. This anecdote reveals Marx's anxieties about the intelligibility and reception of his complex work, as well as his self-perception as a creative artist engaged in a monumental task.
Marx's initial plan for Capital, drawn up in 1857, was much broader than the published volumes. It envisioned six books: on capital, landed property, wage-labour, the state, international trade, and the world market and crises. This plan was revised several times. The formerly central concept of "capital in general"—which abstracted from the competition between many capitals—was abandoned after 1863, leading to a new structure for the work. By 1865–66, the structure had been modified to a four-volume work on capital, with the first three volumes corresponding to the ones published, and the fourth volume dedicated to the history of economic theory. Topics such as wage-labour and landed property were integrated into Volume I and Volume III (analysis of ground rent), respectively. While the volumes of Capital are often considered Marx's complete work, they only correspond to the first book of his scrapped six-book plan. The conceptual apparatus he developed, particularly in its opening chapters, was intended to lay the foundation for a much broader analysis of topics such as the state, the world market, and crises, which never came to fruition.
Synopsis
Volume I: The Process of Production of Capital
Volume I, published in 1867, is Marx's most extensive and historically detailed work, focusing on the immediate process of production of capital. It lays out the foundational categories of his critique of political economy and traces the ways in which surplus value is generated through the exploitation of labour.
Part I: Commodities and Money
Marx begins his analysis with the commodity as the elementary form of wealth in capitalist societies, where wealth "appears as" an "immense collection of commodities". He establishes its dual character: it has a "use-value", satisfying some human want or need, and an "exchange-value", the quantitative proportion in which it exchanges for other commodities. This commensurability in exchange, Marx argues, points to an underlying common element: "value".
The "substance" of value is congealed "human labour in the abstract", a "social substance" that commodities possess not individually but "communally" through their relationship in exchange. Crucial to Marx's theory is the distinction between "concrete labour" (specific purposeful activities like weaving or tailoring) and "abstract labour" (labour as a general social mediation). Abstract labour is not a physiological expenditure but a historically specific social category unique to capitalism, where labour serves as the means by which individuals acquire the products of others. The magnitude of value is determined by "socially necessary labour time" – the average time required to produce a commodity under normal conditions of production with the average degree of skill and intensity prevalent in that society. For a commodity to have value, its labour must be useful, meaning it must produce a use-value that someone wants, needs, or desires.
This section introduces the concept of the "fetishism of commodities", where the social relations between producers "assume... the fantastic form of a relation between things". This "value-objectivity", which Marx describes as "spectral" or "phantom-like", is a "socio-natural property" that appears to belong to commodities themselves but is in fact the result of a specific social structure. The market system and "money-forms" disguise these real social relations, making them appear as objective properties of the commodities.
The exchange process itself necessitates a universal equivalent, a "money commodity" (historically gold and silver). Marx traces the conceptual development of the form of value from the simple or accidental form, through the expanded and general forms, to the money form, arguing that this development is not historical but logical. Money serves as a measure of value (allowing commodities to express their values as price) and as a medium of circulation (facilitating the exchange of commodities, C-M-C). These two functions are contradictory: as a measure of value, money should be stable (like gold), but as a means of circulation, it needs to be efficient and adaptable, leading to the use of tokens and credit money. The circulation of commodities C-M-C (selling in order to buy) contains the formal possibility of crises, as the sale (C-M) and the purchase (M-C) are separated in time and space, meaning there is no automatic guarantee that a sale will be followed by a purchase. Money also functions as a hoard (a store of value), as a means of payment (for settling debts, introducing the creditor-debtor relation), and as "world money" in international trade.
Part II: The Transformation of Money into Capital
Marx then examines how money is transformed into capital. The simple circulation of commodities is C-M-C (selling in order to buy another commodity of equivalent value). Capital, however, circulates as M-C-M' (buying in order to sell dearer), where M' is M + ΔM, the increment ΔM being "surplus value". Capital is thus defined not as a thing (like money or machines) but as a process: "value in motion", specifically "self-valorising value" which becomes an "automatic subject". The capitalist, as the "conscious bearer" of this movement, is driven by the "unceasing movement of profit-making".
Marx argues that surplus value cannot arise from the sphere of circulation if equivalents are exchanged (M-C and C-M both adhering to value equivalence). While individual capitalists might cheat by buying cheap or selling dear, this merely redistributes existing value. The problem is to explain how the capitalist class as a whole can extract surplus value while adhering to the laws of commodity exchange. The solution lies in finding a unique commodity whose use-value is itself a source of more value than it costs. This commodity is "labour power", the capacity to labour. For labour-power to be available as a commodity, two conditions must be met: the labourer must be a "free proprietor" of their labour-power, able to sell it for a definite period; and the labourer must be "free" in the double sense of not possessing the means of production, thus having no other commodity to sell and being compelled to sell their labour-power to survive. This "double freedom" is the result of a historical process of "primitive accumulation" which divorces the producers from the means of production.
The value of labour-power is determined, like that of any other commodity, by the labour-time necessary for its reproduction. This includes the means of subsistence required to maintain the labourer in their normal state as a working individual and to reproduce the working class. Marx emphasises that this value contains a "historical and moral element", varying according to the level of civilisation, the habits and expectations of the working class, and the outcomes of class struggle. The capitalist purchases labour-power at its value, and then consumes its use-value in the labour process. The "secret of profit-making" is that the value created by the labourer in the production process is greater than the value of their own labour-power.
Part III: The Production of Absolute Surplus-Value
Marx moves from the sphere of circulation ("a very Eden of the innate rights of man") into the "hidden abode of production". The capitalist production process is a unity of the "labour process" (the purposeful activity of producing use-values) and the "valorisation process" (the process of creating value and surplus-value). In the labour process, the capitalist controls the work and owns the product. This generates a "rebellious attitude" in the worker, who is now subordinated to an external purpose.
Capital advanced is divided into "constant capital" (c) – the value of the means of production (raw materials, auxiliary materials, and instruments of labour) – and "variable capital" (v) – the value laid out in purchasing labour-power. Constant capital merely transfers its existing value to the new product, while variable capital, through the expenditure of living labour, creates new value. The new value created is greater than the value of the variable capital (v); this excess is surplus value (s). The total value of the commodity is thus c + v + s. The "rate of surplus value" (s/v) is the measure of the exploitation of labour-power. It expresses the ratio of "surplus labour-time" (the time the worker labours beyond what is necessary to reproduce the value of their labour-power) to "necessary labour-time" (the time required to reproduce the value of labour-power).
The working day is the site of a struggle between the capitalist class (seeking to maximise its length) and the working class (seeking to limit it). Capital, as "dead labour which, vampire-like, lives only by sucking living labour", has an inherent drive to extend the working day beyond its physical and social limits. This struggle is not resolvable by appeals to the "rights" of commodity exchange, as both capitalist and worker can claim their rights as buyer and seller respectively. "Between equal rights, force decides", leading to a historical struggle, exemplified by the fight for the Factory Acts in Britain. Marx details the often brutal conditions and excessive hours imposed on workers, particularly women and children, in various industries. The establishment of a "normal working day" is thus a product of protracted class struggle and state intervention, influenced by factors such as the need for a healthy workforce and military conscripts.
"Absolute surplus-value" is produced by prolonging the working day, thus extending surplus labour-time, given a constant necessary labour-time. The "mass of surplus-value" is the rate of surplus-value multiplied by the number of labourers employed.
Part IV: The Production of Relative Surplus-Value
"Relative surplus-value" is produced by shortening necessary labour-time, typically through increases in the productivity of labour in those industries that produce wage goods. If the value of the means of subsistence falls, the value of labour-power also falls, allowing the capitalist to appropriate a larger share of the working day as surplus labour-time, even if the length of the working day remains constant or is shortened.
Individual capitalists are driven by the coercive laws of competition to seek an "extra surplus-value" (or extra profit) by introducing new technologies or organisational methods that make their individual value of production lower than the social average. This extra surplus-value is ephemeral, disappearing once the new methods become generalised. This constant hunt for ephemeral extra surplus-value is the immanent drive within capitalism for perpetual technological and organisational dynamism. Marx notes that a rise in the physical standard of living of workers (more use-values) can be compatible with a rising rate of exploitation if productivity increases sufficiently.
Marx then examines the specific methods of producing relative surplus-value:
Cooperation: The bringing together of many workers under the command of a single capitalist creates a new "social productive power of labour", a collective force greater than the sum of individual powers. This collective power appears as a productive power of capital itself. The capitalist's function of direction and supervision becomes necessary, but it is also a function of exploitation, a "despotic" command.
Division of labour and manufacture: Manufacture, based on handicraft skills, involves breaking down the production process into specialised, partial operations performed by "detail labourers". This increases productivity but "converts the worker into a crippled monstrosity" by suppressing a "whole world of productive drives and inclinations". A hierarchical structure of labour-powers emerges, and the intellectual potentialities of production become concentrated in capital. Marx distinguishes the division of labour in the workshop (despotic and planned) from the division of labour in society (anarchic, mediated by market exchange).
Machinery and large-scale industry: The introduction of machinery revolutionises the technical basis of production. The machine, as a tool taken out of the worker's hands and incorporated into a mechanism, confronts the worker as "capital, dead labour, that dominates, and pumps dry, living labour-power". The skill of the worker passes over to the machine, and the worker becomes a mere appendage to the "automatic system of machinery". Machinery cheapens commodities (and thus labour-power) and is a powerful weapon in the hands of capital for prolonging the working day (to recoup its value before obsolescence), intensifying labour, and suppressing worker resistance. Marx discusses the struggle between worker and machine, noting that workers eventually learn to distinguish between machinery itself and its capitalist employment. The Factory Acts, while limiting hours and regulating conditions, also accelerate the concentration of capital and the generalisation of the factory system. Large-scale industry creates the material conditions for a "new and higher synthesis" of agriculture and industry, but under capitalism, this often leads to the ruining of the soil and the worker. Marx notes the contradiction that capitalism requires an increasingly flexible, adaptable, and educated workforce ("the totally developed individual") while simultaneously degrading and stultifying labour.
Part V: The Production of Absolute and Relative Surplus-Value
In this part, Marx synthesises the discussions on absolute and relative surplus-value. Capitalists employ a variety of strategies to increase the rate and mass of surplus-value, often combining methods. For example, increases in productivity (relative surplus-value) can be used to intensify labour (a form of absolute surplus-value if the working day remains constant). The "form-giving fire" of living labour is the ultimate source of surplus-value, and capital's drive is to appropriate as much of this unpaid labour as possible. Marx revisits the idea of the "collective labourer", emphasising that as the scale and cooperation of production increase, the concept of productive labour expands to include not only those directly working on the material but also those involved in the general coordination and scientific application within the production process, such as engineers and managers. However, he narrows the definition from capital's perspective: "the only worker who is productive is one who produces surplus-value for the capitalist".
Part VI: Wages
Marx analyses the various forms of wages, arguing that they obscure the underlying reality of exploitation. He shows that the wage is the phenomenal form of the value, or price, of labour-power, yet it appears as the price of labour itself.
Time wages: Wages appear as the price of labour for a certain period (e.g., per hour or day). This creates the illusion that all labour is paid labour, concealing the distinction between necessary and surplus labour-time.
Piece wages: Wages are paid per piece produced. This form is well-suited to capitalist exploitation, as it intensifies labour and encourages workers to overwork themselves, while making supervision less necessary. It fosters competition among workers and obscures the fact that the price per piece is ultimately determined by what the average worker can produce in a given time.
National differences in wages: Marx briefly considers how wage levels differ between countries, influenced by factors such as historical development, the cost of subsistence, the intensity of labour, and the value of money. He notes that higher wages in one country might correspond to a higher rate of surplus-value if productivity is also much higher.
Part VII: The Process of Accumulation of Capital
This part examines how surplus-value is reconverted into capital, leading to capital accumulation on an ever-expanding scale. Marx's analysis here operates under specific assumptions: a closed system (no foreign trade), no problems of realising commodities at their values, and the exclusion of the division of surplus-value into rent, interest, and industrial profit.
Simple reproduction: Marx first considers a hypothetical scenario where the entire surplus-value is consumed by the capitalist as revenue, meaning capital is merely reproduced on the same scale. Even under these conditions, he argues, the continuity of the production process means that all capital eventually becomes capitalised surplus-value. The worker constantly produces the capital that exploits them, and the capital relation itself is reproduced.
Expanded reproduction (accumulation): Capitalists are driven by the "historical mission" of "accumulation for accumulation's sake, production for production's sake". Part of the surplus-value is capitalised, i.e., used to purchase additional means of production and labour-power, leading to production on an expanded scale. Marx critiques classical political economy's "erroneous conceptions" of accumulation, particularly its neglect of the need to produce additional means of production (constant capital) alongside additional means of subsistence for an expanded workforce. The capitalist's drive to accumulate is presented as an objective necessity imposed by competition, rather than mere subjective greed.
The general law of capitalist accumulation: Accumulation affects the demand for labour. If the "organic composition of capital" (c/v, the ratio of constant to variable capital, reflecting productivity) remains constant, accumulation leads to increased demand for labour-power, potentially raising wages. However, the general tendency of capitalist accumulation is towards a rising organic composition of capital, as capitalists introduce labour-saving machinery in pursuit of relative surplus-value and to gain competitive advantage. This means that the demand for labour falls relative to the magnitude of the total capital.
Capitalist accumulation "constantly produces... a relatively redundant working population, i.e. a population which is superfluous to capital's average requirements for its own valorisation, and is therefore a surplus population". This "industrial reserve army" (or "relative surplus population") is a necessary product of accumulation and a condition for its existence, providing a readily available supply of labour for expansion and exerting downward pressure on wages. Marx identifies different forms of the reserve army: the "floating" (e.g., temporarily unemployed factory workers), the "latent" (e.g., agricultural populations being drawn into industry, or women and children entering the workforce), and the "stagnant" (e.g., irregularly employed workers, including those in the "sphere of pauperism" like vagabonds and criminals).
The "absolute general law of capitalist accumulation" is that "in proportion as capital accumulates, the situation of the worker, be his payment high or low, must grow worse". Marx's argument here concerns the relative impoverishment of the working class: workers receive a smaller part of the new value they produce, and their needs as human beings are increasingly denied by the alienating and dehumanising production process. This leads to an "accumulation of misery, the torment of labour, slavery, ignorance, brutalisation and moral degradation at the opposite pole" to the accumulation of wealth.
Part VIII: So-Called Primitive Accumulation
In the final part of Volume I, Marx addresses the historical origins of the capital relation, a process he terms "primitive accumulation". This process is "primitive" because it forms the pre-history of capital and the capitalist mode of production, establishing the fundamental conditions for capitalist accumulation to begin. Marx contrasts his historical account with the "idyllic methods" portrayed by classical political economy, which he dismisses as a "children's fable" that depicts the emergence of capital and wage-labour as a gradual and peaceful result of diligence and frugality. For Marx, "in actual history, it is notorious that conquest, enslavement, robbery, murder, in short, force, play the greatest part".
