 Socialist feminism fell largely out of fashion during the latter part of the 20th century, fueled in part by the rise of poststructuralism, the prominence of identity and recognition based politics, and the emergence of a neoliberal consensus (for a trenchant critique of these developments, see Fraser 1996 and 2013). However, in the wake of the global financial crisis of 2008, socialist feminism, now often referred to as Social Reproduction Theory (SRT), has made a comeback. SRT has a long history, with important early contributions by Silvia Federici (1975) and Maria Mies (1986) and connections to the Italian wages for housework campaign that began in the 1970s; for more recent discussions, see Tithi Bhattacharya (2017), Federici (2014 and 2019), and Alessandra Mezzadri (2019). SRT is a Marxist feminist project that orients itself to a question that remains implicit in Marx's theory of value: how is labor power, which is the source of value and thus of exploitation in Marx's account, itself produced, reproduced, and maintained? SRT maintains that labor power is produced and reproduced outside of the official economy, largely through women's unpaid labor within the family or domestic sphere. For social reproduction theorists, the production of goods and services is thus possible only on the basis of (largely) unpaid social reproduction, which includes childbirth, domestic work, caring for children, the elderly and others who cannot work for wages, and so on. For Federici, this represents an ongoing process of expropriation akin to Marx's notion of primitive accumulation (Federici 2014). Social reproduction theorists understand production and reproduction as parts of an integrated system; indeed, they view the distinction between the two as ultimately misleading inasmuch as it obscures the ways in which social reproduction is itself productive of value (Mezzadri 2019). For a related attempt to understand capitalism as a social totality whose relations of production are made possible by the expropriation of socially reproductive labor, environmental resources, and the labor of dispossessed and colonized peoples, see Fraser in Fraser and Jaeggi (2018).
