Millions of college grads saddled with debt and no job prospects would likely agree with this estimation.

Only 150 of 3500 U.S. Colleges Are Worth the Investment: Former Secretary of Education

The U.S. is home to some of the greatest colleges and universities in the world. But with the student debt load at more than $1 trillion and youth unemployment elevated, when assessing the value of a college education, that’s only one part of the story.

Former Secretary of Education William Bennett, author of Is College Worth It, sat down with The Daily Ticker on the sidelines of the Milken Institute’s 2013 Global Conference to talk about whether college is worth it.

“We have about 21 million people in higher education, and about half the people who start four year colleges don’t finish,” Bennett tells The Daily Ticker. “Those who do finish, who graduated in 2011 – half were either unemployed or radically underemployed and in debt.”

That average student loan balance for a 25-year-old is $20,326, according to the Federal Reserve of New York. Student debt is second largest source of U.S. household debt, after only mortgages.

Bennett assessed the “return on investment” for the 3500 colleges and universities in the country. He found that returns were positive for only 150 institutions.
