Student loans are 100% of the problem.
Step one: No more Federal guaranteed loans, for any reason. Want taxpayer college money, go to West Point.
Step two: Make any college or university accepting borrowed money for tuition or books co-sign the loan.
Step three: Make any loan for the purposes of tuition or books dischargeable in bankruptcy.
Step two is brilliant.
Affirmative action is a large part of the problem; many of the “students” are unqualified semi-literates put there by the government in the hopes they won’t breed.
