Interesting point about the mortgage crisis

From Matthew Yglesias at The Atlantic:

Part of the rah-rah media atmosphere of the boom years was that price increases were defined as "good," which meant that anything that led to price increases, including a tightening supply of places where one could live and then swiftly get around to interesting spots, was also defined as good. In the real world, though, a shortage of desirably located dwellings is no more a good thing than is any other kind of shortage. The question is what can be done about it?
