People think of a business cycle, which is a boom followed by a recession and then automatic stabilizers revive the economy. But this time we can't revive.

The fact that you have government-guaranteed student loans has created a whole new sector in the American economy that didn't really exist before - private for-profit universities that sell junk degrees that don't help the students. They promise the students, "We'll help you get a better job. We'll arrange a loan so that you don't have to pay a penny for this education." Their pet bank gets them the government-guaranteed loan, and the student may get the junk degree, but doesn't get a job, so they don't pay the loan.
