Many of those college students would have done better to go to a technical school for better job prospects at lower cost. Those who did go to college had better have put some thought into picking their major.

Below are some charts and tables on college underemployment, published with permission from the Center For College Affordability.

48% of working college graduates are underemployed. This chart will get worse over the next decade.
