Marx criticized bourgeois economics for not considering the worker as a “human being” but only as a “factor of production.” He showed how Neoclassical economics systematically ruled out social relations that constitute and produce the working class: such as race, gender, sexuality, historical culture, etc. Marx’s own work, Capital, however, can be said to fall short of Marx’s own guidelines. This talk is about how Social Reproduction Theory can enrich Marx’s own understanding of capitalism and thus help restore to our theory the historical potential of the global working class.
