Core argument
Korpi (1983) argued that in capitalist democracies capitalists hold economic resources while workers hold political resources of numbers and organization. The core claim is that where union density is high and left parties govern for long periods, generous welfare states emerge that politically correct market income inequality. He called this the democratic class struggle.
Evidence and extensions
Esping-Andersen (1990) traced three welfare regimes, liberal, conservative and social democratic, to differences in class mobilization and coalitions. Huber and Stephens (2001) showed that cumulative left government predicts welfare spending and redistribution, and Bradley and colleagues (2003) confirmed effects of left parties and unions on redistribution. Korpi and Palme (1998) identified the paradox of redistribution: universal programs win broader support and end up redistributing more than programs targeted at the poor.
Critiques and debates
Employer-centered approaches argued that some firms backed social insurance to build skills, linking to varieties of capitalism. Iversen and Soskice (2006) offered an electoral-institutions account in which proportional representation eases center-left coalitions and raises redistribution. Korpi (2006) replied that employers were mostly reluctant consenters.
FAQ

- What is the paradox of redistribution?
- The finding that universal programs covering everyone gain broader support and so redistribute more than programs aimed only at the poor.
