Yes, but that doesn't mean the people who had houses that lost value are screwed. It just means that they didn't pocket as much profit as they could have. They bought a value and a rate they could afford. They're no more or less screwed if the value of the house goes down. They're screwed if they can't pay the mortgage. Lots of people are screwed by high housing costs. The only rational conclusion is to lower housing costs. I say this as someone paying a mortgage.
