This introductory chapter provides an overview of the three worlds of relief created by the intersection of labor, race, and politics in welfare state development. Blacks, Mexicans, and European immigrants inhabited three separate worlds in the first third of the twentieth century, each characterized by its own system of race and labor market relations and its own distinct political system. From these worlds—and each group's place within them—three separate perspectives emerged about each group's propensity to become dependent on relief. The distinct political systems, race and labor market relations, and ideologies about each group's proclivity to use relief, in turn, influenced the scope, reach, and character of the relief systems that emerged across American communities.
