The mid-twentieth century is often seen as the period in which the left learned to love the state, as earlier pluralist ideas – federalism, syndicalism, guild socialism – were relegated to the margins of socialist and liberal ideologies by new state-centred reform projects organized around the welfare state, nationalization, and economic planning. But this brief social democratic moment was itself delegitimized shortly thereafter and replaced by a neo-liberal discourse grounded on the sovereignty of the individual and an abiding hostility to the state. This chapter argues that this is in fact a misleading account of the fate of the socialist pluralist tradition, for two reasons. First, socialists and progressive liberals explicitly theorized the mid-century social settlement as a pluralist enterprise, albeit one that was much less ambitious than the equivalent projects envisaged by guild socialists and syndicalists earlier in the century. Second, the neo-liberal critique of social democracy was articulated as an attack on the existence of certain associations in civil society that were held to threaten both individual liberty and the state.
