Under discussion on The Glenn Show is Brink's new book, Human Capitalism: How Economic Growth Has Made Us Smarter and More Unequal. Glenn asks Brink how his argument differs from that of Murray and Herrnstein in The Bell Curve. Brink explains how the human capital divergence contributes to growing inequality, and how the complexity of the modern world exacerbates class differences. Can education overcome the class gap? Brink describes the problems with "working class culture." Brink closes with proposals for educational and economic reform to improve the lives of the lower class.
