Baby boomers born in 1955 had 2 more years of schooling than their parents by age 30. By contrast baby boomers born in 1980 had 8 months more schooling than their parents by age 30. This is the shown in a study by Harvard professors Goldin and Katz. A big part of the problem is the high dropout rates at some high schools in the U.S. Another part of the problem which is growing today is the high cost of tution discouraging students from going to college, and the large student debt being borne by parents. Student debt reached $1 trillion in the U.S. by 2012.
