The United States has been underproducing college-going workers since 1980. Supply has failed to keep pace with growing demand, and as a result, income inequality has grown precipitously. From 1915 to 1980, supply grew in tandem with demand. But, starting in 1990, the share of college-educated young people in the workforce rose very slowly. If the nation continues to underproduce college-educated workers, the large and growing gap between the earnings of Americans of different educational attainment will grow even wider. This paper suggests that adding an additional 20 million postsecondary-educated workers over the course of the next 15 years will make the nation's level of educational attainment comparable with other developed nations, help meet the economy's need for efficiency, and reverse the growth of income inequality.
