The OP needs to ask....what about all the parents who saved for college and can now use the money for other things?
Warren's a horrible politician, but the charges are suspicious imo and smack of a dead fish being planted. Anyone going to college/university (public or private) is getting a mix of aid, loans and having to come up with cash. If you really were able to finance your kids' educations without loans, you didn't need the help. Either that or you really did screw up by paying out in cash what you could have gotten in programs like teach for America.
Warren's plan is a bit screwy though. But there are tens of thousands of young people whose careers got lost in the great recession. Even my daughter's generation that is ten years removed from that debacle fears it could be her future (heh) too.
