On closer scrutiny, however, it’s not entirely clear how well our current interest in inequality (especially income inequality) rhymes with Marx’s own theory, or the ideas that dominated social-policy debates in decades following the Second World War. In fact, one could even argue that our current focus on income and wealth inequality, while crucial to any progressive agenda, also misses some of the most important aspects of the nineteenth-century critique of capitalism. At that time, “income inequality” was an elusive and at best ancillary term. In fact, the “monetization” of inequality is actually a relatively recent way of seeing the world — and, aside from its obvious strengths, it is also a way of seeing that, as the historian Pedro Ramos Pinto noted, has considerably “narrowed” the way we think about social justice.[...]
Even here, however, Marx still thought of inequality in terms of classes that were produced by capitalism, rather than in individual terms. For Marx, it seems, the problem was not exactly how income was distributed among people but how capitalism itself tended inherently toward the immiseration of workers and the production of “a relatively redundant population of laborers.” In that sense, as Samuel Moyn has observed, it is quite clear that Marx never really embraced any conception of “distributional equality” because, within capitalism, it would always be “hostage to class rule.” Rather, he tried to imagine a post-market society. Of course, Marx’s ideal never fully came into existence in Western Europe or the United States, but his analysis of the causes of inequality, rooted in a rich literature of nineteenth-century thinkers and economists like Eugène Buret or Charles Fourier, would prove an enduring influence on how to think about inequality, well beyond the circle of self-proclaimed Marxists.[...]
Of course, the labor-centered orientation of these new institutions relied essentially on the unpaid labor of women as domestic workers in households sustained by the “Fordist family wage.” Consequently, to various degrees depending on the country, it shaped a model of citizenship with significant exclusionary features for women or the immigrant labor force. However, in contrast to nineteenth-century poor relief systems, this new categorical architecture was, importantly, to be organized against the market rather than acting upon its margins. More importantly, demands and struggles for its effective universalization intensified in the decades following the war, slowly extending its benefits to a larger part of the population.[...]
By the early 1970s, in both the US and Europe, the spectacular emergence of the “poverty issue” would strongly encourage a vision of social justice focused on a monetary conception of poverty. Indeed, the focus on the establishment of a “floor” below which nobody could fall rapidly pushed aside any discussion of building ceilings or reducing market dependency. Guaranteed income proposals and negative-income-tax programs became widely popular among policymakers and political parties across the political spectrum, as a way to finally fight poverty while shedding any emphasis on large macroeconomic interventionism and complicated welfare schemes.
