If you want to get a name as an economic seer, try this one. The next subprime crisis will come from defaults on student debts, starting with for-profit colleges and rising to the Ivy League. The parallels with housing are striking. In both, the written warnings aren't understood, especially on penalties and interest rates. And in both, it's assumed that what's being bought will rise in value, in one case the real estate, in the other the salaries which will accrue with a degree. One bubble has burst; the second is already losing air. Still, there's a difference. With mortgage defaults, banks seize and resell the home. But if a degree can't be sold, that doesn't deter the banks. They essentially wrote the student loan law, in which the fine-print says they aren't "dischargable."
