I think this is a way for the top 1 percenters to keep those at the bottom from rising up. If people at the bottom are able to stay in their homes and not have to make mortgage payments, then they can survive on welfare and food stamps. The top 1 percenters want those at the bottom to feel guilt as opposed to anger. So far it’s working.
This squeezes the middle class and causes the middle class to direct their anger to those at the bottom (hello Tea Party!) as opposed to those at the top.
