Buffett: "Dumb lending always has its consequences. It's like a disease that doesn't manifest itself for a few weeks, like an epidemic that doesn't show up until it's too late to stop it Any developer will build anything he can borrow against. If you look at the 10Ks that are getting filed [by banks] and compare them just against last year's 10Ks, and look at their balances of 'interest accrued but not paid,' you'll see some very interesting statistics [implying that many homeowners are no longer able to service their current debt]."
