re: When did the idea all kids go to college begin?

Not everyone is cut out for college, I agree with that. But, to say that college tuition isn't worth it, is a broad generalization. There are many careers that require individuals with a college degree (or two). Many of these careers make a salary that would justify the cost of college. I think I spent less than 50k (maybe a bit more) on two degrees. I'd definitely say that they've already paid off (5 years out).
