Video Marxist economics and the crisis of capitalism

Marxist Theory · 2026-05-13

Core Argument¶

This talk argues that Marx's economic categories — above all the labour theory of value and the theory of surplus value — are not merely abstract philosophical propositions but the essential tools for understanding why capitalism is inherently crisis-prone. The central claim is that Marx completed the work begun by classical political economy, resolving its contradictions and thereby providing a scientific basis for explaining periodic economic breakdowns as rooted not in external shocks or policy errors but in the internal dynamics of capital accumulation itself. The crisis of capitalism, on this account, is not a malfunction but a necessary expression of the system's fundamental contradictions.

Theoretical Grounding¶

The analysis is grounded in Marx's critique of political economy as developed in Capital, particularly Volume I's exposition of the labour theory of value and the distinction between labour and labour-power. Sewell draws on Marx's debt to and break from Smith and Ricardo: the former identified labour as the source of value but could not explain how profit arose consistently with the law of value; the latter recognised class conflict but could not account for the origin of surplus value under conditions of equal exchange. Marx's solution — that the worker sells labour-power, not labour, and that the value of labour-power is less than the value it produces — resolves this contradiction and opens the way to understanding exploitation as a structural feature, not a market distortion.

The talk situates itself within the classical Marxist tradition that treats the tendency of the rate of profit to fall as the most fundamental law of political economy, though it does not develop the law in formal detail. It also draws implicitly on the distinction between use-value and exchange-value, and on the concept of the reserve army of labour, to explain why crises are not merely possible but inevitable under capitalist relations of production.

Conjunctural Relevance¶

Delivered in 2018, the talk was framed around the 200th anniversary of Marx's birth, but its conjunctural significance lies in its positioning against the backdrop of the 2008 global financial crisis and its aftermath. Sewell references the decade of stagnation, austerity, and declining living standards that followed the crash as empirical confirmation of Marx's predictions. The talk does not engage with the specificities of post-2008 monetary policy — quantitative easing, near-zero interest rates, the ballooning of fictitious capital — but it provides the theoretical framework within which those phenomena can be understood: as attempts to postpone the inevitable reckoning with overaccumulation and falling profitability.

The conjuncture is also defined politically: the talk is part of a broader effort by the RCI to counter reformist and Keynesian narratives that treat crises as correctable through state intervention. Sewell insists that no amount of regulation or demand management can abolish the law of value, and that the only resolution to capitalist crisis is the revolutionary overthrow of the system itself.

Where the Argument Continues¶

This talk is an introductory exposition and therefore leaves several crucial questions underdeveloped. The tendency of the rate of profit to fall is invoked but not formally derived or empirically substantiated; the relationship between the falling rate of profit and the concrete forms of crisis (financial crashes, recessions, stagflation) is gestured at but not traced in detail. The argument continues in several directions within the IDOM corpus:

Alan Woods, The Reformist Trap (marxist.com): develops the political conclusion that reformist strategies cannot resolve capitalist contradictions.
Rob Sewell, In Defence of the Law of Value (Socialist Appeal, 2019): provides a more detailed defence of the labour theory of value against academic critiques.
Against the Stream episodes on the 2008 crash and its aftermath: apply the theoretical framework to concrete economic history.
Marx's Capital, Volume III, Part III: the classical source for the law of the tendency of the rate of profit to fall, which the talk presupposes but does not expound.

Connections¶

The talk should be read alongside:

Isaak Illich Rubin, Essays on Marx's Theory of Value: for a rigorous treatment of the value-form and the fetishism of commodities.
Ernest Mandel, Late Capitalism: for an attempt to apply Marx's crisis theory to the post-war period.
Michael Heinrich, An Introduction to the Three Volumes of Karl Marx's Capital: for a contrasting, more sceptical reading of the law of the tendency of the rate of profit to fall.
David Harvey, The Enigma of Capital: for a contemporary application of Marxian categories to the 2008 crisis, though from a position the RCI would critique as insufficiently revolutionary.

The talk also connects to the broader tradition of political economy from Smith and Ricardo through to Marx, and to the polemical tradition within Marxism that distinguishes scientific socialism from utopian socialism and reformism.

Key Quotes¶

"Marx took the ideas of the classical economists, Adam Smith and David Ricardo, and developed them to their logical conclusion. He resolved the contradictions that they could not solve, and in doing so, he provided a scientific explanation of how capitalism works — and why it doesn't work."
"The worker sells not their labour, but their labour-power — the capacity to work. The value of that labour-power is determined by the cost of maintaining and reproducing the worker. But the value that labour-power creates in the course of a working day is greater than that. That difference is surplus value — and that is the source of all profit, all interest, all rent."
"Crisis is not an accident. It is not the result of bad policy or greedy bankers. It is the necessary expression of the contradictions inherent in the capitalist mode of production itself."
"The law of value operates behind the backs of the producers. It is a blind, anarchic force that asserts itself through crisis. You cannot regulate it away. You cannot vote it out of existence. The only way to abolish the law of value is to abolish the system that gives rise to it."
"Marx showed that capitalism, far from being the end of history, is just a transitory phase in human development — a phase that has outlived its usefulness and now stands as a barrier to further human progress."
"The working class is the only class capable of overthrowing capitalism, because it is the only class that has the power to stop production. But to do that, it needs a revolutionary consciousness — and that consciousness can only come from the scientific understanding that Marxism provides."
