From the Fordist industrial society to the post-Fordist service society, many new characteristics emerged in the welfare states. In terms of occupational stratification, the emergence of great number of professional jobs in the process of servitization as well as its demand for skilled workers had made education and other social policies increasingly become the decisive forces for class mobility. From the perspective of income distribution, globalization, deregulation, deindustrialization combined with the composite issues of aging, servitization and urbanization have led to polarized or uneven income distribution in almost all welfare states, and the middle class declined generally. Efforts aimed at balancing efficiency and equity magnified the divergence of welfare states. In the light of the difficulties encountered by developed countries in the pursuit of modernization, balanced industrial development and co-ordination between economic and social policies are the cornerstone of common prosperity.
