Book excerpt: With the latest data on income, wealth, earnings, and residential segregation by income, The American Class Structure in an Age of Growing Inequality, Tenth Edition describes a consistent pattern of growing inequality in the United States since the early 1970s. Focusing on the socioeconomic core of the American class system, author Dennis L. Gilbert examines how changes in the economy, family life, globalization, and politics are contributing to increasing class inequality. New to this Edition “The Class Basis of Trump's Victory” looks at why for the first time since before the 1932 election, the Republican presidential candidate won a greater proportion of the working class vote than the Democratic opponent. Addresses the role of technology and other factors in the decline of manufacturing employment and how the trend is crucial for understanding growing inequality and changes in working class family life. Offers international comparisons to show how the U.S. compares with other wealthy nations on social mobility and poverty, and questions our conception of the U.S. as a uniquely open society.
