Seems it would be best to make student debt defaultable. That way, instead of making taxpayers cover these loans, colleges and traditional lenders (government should get out of the loan business) would direct students toward productive majors with a good chance of providing enough compensation to make loan repayment likely. As it is, the student loan program is an incentive for colleges to jack up prices, without much incentive to make its graduates productive members of society.

Not to mention making those who skipped college and just started working a trade to pay for the education of those that went to school and studied useless topics. Imagine, construction workers, auto mechanics, firefighters, and retail workers having to pay for someone else to go to college to study French, political science, or gender studies.
