In this session of Yale instructor Paul North's chapter by chapter study of Marx's Capital, Volume 1, the lecture examines the role of technology in reshaping labor and explains the counterintuitive dynamic in which increased individual output can coincide with declining relative wages. North traces how Marx describes the transformation of the mode of labor as machinery and increasingly organized production techniques enter the workplace. Building on the prior class's introduction of relative surplus value, the lecture develops the connection between technological change and the restructuring of the working day. The course continues its close, chapter by chapter reading of the 1872 text throughout.
