Immiseration thesis
In Marxist theory and Marxian economics, the immiseration thesis, also referred to as emiseration thesis, is derived from Karl Marx's analysis of economic development in capitalism, implying that the nature of capitalist production stabilizes real wages, reducing wage growth relative to total value creation in the economy. Even if real wages rise, therefore, the overall labor share of income decreases, leading to the increasing power of capital in society.
The immiseration thesis is related to Marx's analysis of the rising organic composition of capital and reduced demand for labor relative to capital equipment as technology develops.
The law of increasing misery is a concept central to Marxist theory, suggesting that capitalism inherently leads to a decline in the standard of living for the working class, even if wages may technically rise, while simultaneously enriching the capitalist class. This theory posits that the nature of capitalist production, characterized by the increasing exploitation of labor, will ultimately result in a greater concentration of wealth and power in the hands of a smaller, capitalist elite, leaving the working class increasingly impoverished.
Karl Marx
In Karl Marx's early writings of the 1840s, he was influenced by David Ricardo's theory of wages, which held that wages tended down to a subsistence minimum. As he wrote with Friedrich Engels in the Communist Manifesto, "the average price of wage-labour is the minimum wage. i.e. that quantum of the means of subsistence, which is absolutely requisite to keep the labourer in bare existence as a labourer." This was the "iron law of wages" coined by the socialist Ferdinand Lassalle. Moreover, as he added in On the Question of Free Trade, "as means are constantly being found for the maintenance of labor on cheaper and more wretched food, the minimum of wages is constantly sinking."Under certain conditions, the "iron law" could therefore imply an absolute decline in living standards. However, Marx moved away from this position in the 1850s, and there is no trace of it in his mature economics writings. In Capital, he argued that there was a "historical and moral component" to wages, and that the "value of labour-power.... differs according to climate and the level of social development," depending "not only on the physical needs but also on historically-developed social needs."
This increase in real wages could nevertheless be accompanied by decrease in the labor share, and an increase in the power of the capitalist class. A Marx had recognized as early as Wage Labour and Capital : "If capital grows rapidly, wages may rise, but the profit of capital rises disproportionately faster. The material position of the worker has improved, but at the cost of his social position. The social chasm that separates him from the capitalist has widened." In Chapter 25 of the first volume of Capital, Marx therefore suggested a relative immiseration of workers vis-à-vis capital occurred. Concerning the evolution of the worker's conditions, he wrote:
Marx argued that, in accordance with the labour theory of value, capitalist competition would necessitate the gradual replacement of workers with machines, allowing an increase in productivity, but with less overall value for each product produced, as more products can be made in a given amount of time. This process forms part of the general law of capitalist accumulation, in which the proportion of "constant capital" increases relative to "variable capital" in the production process over time. Marx also noted that this movement is not merely an abstract relation, but that it is a result of class struggle, and it could be temporarily stopped should wages dip below an amount that the proletariat deem acceptable.
