There is plenty of blame to go around for the U.S. housing bubble, but not much of it belongs to Fannie Mae and Freddie Mac.

The FHA's success provides strong evidence that government can and should play a role in the nation's mortgage finance system. It also demonstrates that although government intervention in the economy during the Great Recession was messy, things would have been a lot messier without it.
