This lecture in Yale instructor Paul North's chapter by chapter study of Marx's Capital, Volume 1, examines the ways Marx argues the wage form obscures the underlying nature of exploitation, then moves into Chapters 21 through 24 on accumulation and reproduction. North explains how the accumulation process drives the capitalist system forward and introduces Marx's concept of simple reproduction, the baseline process by which capital renews itself cycle after cycle. The session connects the course's earlier analysis of wages to its closing chapters on how capital reproduces and expands itself over time, continuing the close reading of the 1872 text.
