The U.S. would do itself a huge favour by allowing student debt to be bankruptable. College prices can rise infinitely because there is an unlimited supply of AAA+ debt to feed it. Drop that rating to reality and investors don't buy the debt, loans don't get originated, demand for college at $250k dries up.
Who is going to lend tens of thousands of dollars to an 18 year old with no income, no assets, and no credit?
Since the elimination of the Federal Family Education Loan program in 2010, there has been only one legally-possible lender for Federally-guaranteed student loans.
And they aren't a for-profit corporation, or an entity that evidences much concern for babalncing spending and revenue.
