Esping-Anderson suggests that two questions drive the debate regarding the welfare state. On one hand, authors like T.H. Marshall seek to examine the interaction of class and social welfare, while Esping-Anderson seeks to explain "the causal forces behind welfare-state development." In brief, the author suggests that three independent variables lead to specific welfare regimes: the nature of class mobilization, class-political coalition structures, and the historical legacy of regime institutionalization (29-31). The nature of class mobilization is important in that the way classes mobilize lends to the amount of power it can wield in pursing in its goals. Likewise, the type of class-political coalition structures assist in shaping the political will of various classes in that the coalitions help shape the political capital of various groups. Finally, the historical legacy of regimes is important in that it establishes the strength of weakness of class structures.
The neoliberal welfare regime argues that a free market will abolish class and inequality, while state intervention only strengthens issues of class. The neoliberal model argues that democracy and universal suffrage "would be likely to politicize the distributional struggle, pervert the market, and fuel inefficiencies" (10). In reality, however, the neoliberal regime, through the capitalist system, tends to commodify labor to such an extent that people were unable to survive outside of the market. "Stripping society of the institutional layers that guaranteed social reproduction outside the labor contract meant the people were decommodified" (21). This leads to a difficulty in class mobilization as workers are now nothing more than a commodity to be traded between industries. As such, they are unlikely to gain the political power to translate "mobilized power into desired policies and reforms" (16). Because the neoliberal regime is so reliant on market forces, the state will not intervene unless the familial or market institutions fail. Esping-Anderson refers to this structure as a residual or welfare state. Such a state is characterized by means-tested social assistance. This often punishes and stigmatizes recipients of social welfare and ultimately creates a system of class stratification, particularly between the middle class who relies on market social insurance and the poor who are reliant on state-sponsored social insurance programs (23). Generally, the benefits offered by the neoliberal regime are quite small, as social welfare is seen as a cause of poverty and unemployment, and may lead to laziness and "moral corruption" (42).
The conservative model disagreed with the idea of laisez-faire economic policies. Esping-Anderson suggests that the conservative ideal "was the perpetuation of patriarchy and absolutism as the best legal, political, and social shell for capitalism without class struggle" (10). The conservative paradigm sees a more authoritarian state as better for everyone, as opposed to a more chaotic system based on free markets. As such, the corporatist model created its first social policies because the corporatists saw liberalism democracy and capitalism as destroying the old hierarchical structure. In sum, the conservative ideology does not want to see people starve - commodification is morally repugnant. Rather, they want people to "subordinate self-interest to recognized authority and prevailing institutions" (38). This idea is characterized in the modern social welfare regimes in that it is still reliant on many of the precommodification institutions. Rather than having people be slaves to the market, the corporatist model makes people reliant on the state.
Lastly, the Marxist, or Social Democratic model argues that the accumulation of capital disowns people of property. This leads to deeper class divisions. Additionally, social welfare initiatives like those posed by the neoliberal and corporatist model, according the neo-Marxist paradigm, in fact is more conducive to ensuring class divisions in the name of stability, instead of actually addressing need (55). The Social Democratic model expands on this premise, arguing that by bringing social policy into the parliament, workers will have less dependence on the market and employers. This, coupled with a strong coalition between labor and other groups, farmers perhaps, leads to a system of equality and socialism through the exercise of political power.
Although Esping-Anderson specifically concentrates on the factors leading to various welfare regimes, he does touch on retrenchment, or the repeal of some social welfare initiatives (32-33). As Esping-Anderson argues, and Pierson reiterates, the theory posed by Esping-Anderson should not only explain the emergence of particular types of welfare regimes, but also their subsequent decline, particularly Esping-Anderson suggests that the "class coalitions in which the three welfare-state regime-types were founded, explain not only their past evolution but also their future prospects" (33).
