This contribution focuses on aspects of feminism and gender in Marx’s theory. Marx’s methodology has given us the tools and the categories enabling us to think together gender and class, feminism and anti-capitalism. However, his contribution is an indirect one because Marx never developed a theory of gender. It is important to include the role of reproductive labour, slave labour, migrant labour, labour in the Global South and the unemployed in the critical analysis of capitalism and its division of labour. Reproductive labour is the largest activity on this planet and a major ground of divisions within the working class.
