I worked coops. 3 coops, 20 months total, pay $25 to $30 an hour, still had $35k debt or so on graduation, though none of it private - made it through the crucible with just government loans, and work.
Times change. Even going to state school, even majoring in something that pays well and offers relevant work, it's hardly easy to pay your way through. So it goes.
Good for her, though. A bit too limiting for my tastes but that's her choice.
