The core argument
Clark Kerr and colleagues (1960) argued that the technological logic of industrialism pushes capitalist and socialist societies alike in the same direction. Industrialization brings urbanization, nuclear families, aging populations, and new risks like unemployment and workplace injury, so governments build social insurance and welfare programs. Using data on 64 countries, Harold Wilensky (1975) found economic development and the share of older people were the strongest predictors of welfare spending.
Critiques and alternatives
Convergence theory can't explain why countries at similar income levels have very different welfare systems. Gøsta Esping-Andersen (1990) identified three worlds of welfare capitalism—liberal, conservative, and social democratic—arguing that politics and class coalitions matter. Textbooks contrast convergence theory's functionalist, technologically determinist view with power resources theory, neo-Marxist theories, interest group theory, and state-centered approaches. See also Marshall's theory of citizenship.
