Slate and MR have been talking recently about the fact that unemployment is tied to permanent home ownership: the more mobile your population the lower unemployment will be. This is another reason why the simple economic models I am looking at in my intro classes will never work. Economists for the sake of simplicity will ignore simple things, like that people get attached to their belongings and surroundings. With that said we should not dismiss economics. It is simply unlikely that we will ever get to the equilibriums the models imply.
