Contemporary social and political theorists generally recognise that Marx and Engels’ critical analysis of capitalist society centres on the production of value through the production of things. However, what is often unrecognised in considerations of Marx and Engels is how their analysis is based on the interrelation of production and reproduction. Nevertheless, the implications of this interrelation for feminist critique are explored in the writings of Marx and Engels only tangentially. These implications are developed from Marx’s analysis by Leopoldina Fortunati and Silvia Federici into a singular synthesis of the Marxist and feminist modes of critique. This development deserves greater recognition, and this essay will seek to articulate how the social implications of this interrelation (1) are expressed to a limited extent in the classical texts of Marxism and (2) are developed by Fortunati and Federici into the analytic framework of social reproduction as the core of Marxist-feminist revolutionary struggle.
