INEQUALITY IN EARNINGS AT THE CLOSE OF THE TWENTIETH CENTURY

Median income in the United States has fallen and the distribution of income has grown markedly more unequal over the past three decades, reversing a general pattern of earnings growth and equalization dating back to 1929. Median trends were not the same for all groups—women's earnings generally increased—but the growth in earnings inequality has been experienced by all groups. Even white men employed full-time, year-round—traditionally the most privileged and secure group—could not escape wage stagnation and polarization. These patterns suggest research questions that go beyond conventional sociological interest in racial and gender wage gaps, refocusing attention on more general changes in labor market dynamics. The debates over the origins of the rise in US inequality cover a wide range of issues that can be roughly grouped into four categories: the changing demographics of the labor force, the impact of economic restructuring, the role of political context and institutions, and the dynamics of globalization. We review the empirical literature here, and challenge the field of sociology to reconstruct its research agenda on stratification and inequality.
