Education Slowdown Threatens U.S.

David Wessel & Stephanie Banchero:

Throughout American history, almost every generation has had substantially more education than that of its parents.
That is no longer true.
When baby boomers born in 1955 reached age 30, they had about two years more schooling than their parents, according to Harvard University economists Claudia Goldin and Lawrence Katz, who have calculated the average years of schooling for native-born Americans back to 1876.
In contrast, when Americans born in 1980 turned 30 in 2010, they averaged about eight months more schooling than their parents.
