If this were true, and most kids are doing a cost/benefit analysis about future wealth, then we would say far more engineering/math majors.
Lots of people out here who can actually affect the labor market and affect the way student financing works, and instead of hiring people without college degrees and instead of electing people who can reform financing, they just ask students to take a decidedly stupid bet on not getting a degree. It's a silly way to solve the problem.
