Dare Obasanjo makes more sense than any number of economic "experts" I've been reading recently:

A lot of people have started talking about "stabilizing home prices" and "bailing out home owners" because of underwater mortgages. In truth, easy credit caused houses to become overpriced especially when you consider that house prices were rising at a much faster rate than wages. Despite the current drop, house prices are still unrealistic and will need to come down further. Trying to prevent that from happening is like trying to have our cake and eat it too. You just can't.

Read his whole post - very good stuff, simple common sense.
