Huge difference between student loans and mortgages - the only pain felt will be by the students and taxpayers who will (again!) make the lenders whole on their bad bets: Student loans cannot be discharged even if you declare bankruptcy - while home owners could walk away and hand the keys to the bank. Student loans are guaranteed by the government - the issuers just file for compensation. The sickening part is that…
Taxpayers no longer subsidize private lenders. That ended in 2010.
And there are indirect losses, too: Imagine the government started running a program to pay people $20K+/year (think grants + loans) not to work for four years, provided they paid some of it back at low, capped interest rates. Surely a lot of people would take the government up on that offer, and instead of being productive taxpayers, contributing to the economy and to the treasury, they'll sit around playing XBox. Maybe it turns out that the average college degree program is a better investment than this, even accounting for the lost GDP and tax revenue. But there's no way to be sure, since there's no market at work.
