The way statistics on unemployment, earnings, etc by degree level are being used is disgraceful. It's correlation does not imply causation at the basest level. It's more likely the higher your social and economic background is, the more college you can afford, and the better job you can get.
I see so many people with tons of student debt for a degree that is useless for finding employment. Unless your profession requires a degree (laywer, doctor...) or you can go for free via grant or wealthy parents, most people would be better off entering the work place or starting in a trade. You can always go back to school when you can afford it.
There are A LOT of college graduates out there asking "Would you like fries with that?" to non-grads.
