Why technological progress might paradoxically threaten the growth of capital
In short: In a capitalist system, the very tools designed to boost productivity can create a structural ceiling on profit. This theory suggests that as machinery replaces human labor, the ratio of profit to invested capital naturally shrinks, potentially creating a cycle of periodic or secular economic crises.
Within political economy, crisis theory relies heavily upon the concept of the Rate of Profit to Fall (TRPF). While Karl Marx popularized the concept in Capital, Volume III, economists like Adam Smith and David Ricardo observed it as an empirical reality. The core mechanism lies in the 'organic composition of capital': as industries adopt more efficient, labor-saving technologies, the amount of capital invested in equipment and materials rises relative to the amount of human labor employed. Because value is tied to socially necessary labor, increasing physical productivity through machinery can actually lead to a decline in the average rate of industrial profit over the long term.
Marx argued that this is a general tendency of the capitalist mode of production, driven by a 'labor-saving bias' in technological innovation. To counter this, he identified six factors that can temporarily boost profit rates, including more intense exploitation of workers, reduced wages, the growth of a 'reserve army' of unemployed labor, and the expansion of foreign trade. However, Marx maintained that these counteracting forces are ultimately insufficient to stop the intrinsic decline driven by the increasing dominance of constant capital over variable labor.
The debate remains intense and unresolved. For instance, Japanese economist Nobuo Okishio argued in 1961 that if new techniques reduce unit costs while real wages remain constant, the profit rate should actually increase. Conversely, others suggest that if real wages rise in response to higher productivity, profits are squeezed. Modern scholars also point to external factors like price inflation, government credit policies, and the consolidation of mature industries into oligopolies as critical variables in determining whether the system faces secular stagnation or continued expansion.
