I think the real estate agents and money lending institutions are as much to blame- if not more- for their greed for getting those greedy Americans into those homes they couldn't afford. I mostly feel sorry for the homeowners, having just bought a house myself, I can imagine just how horrible it would be to lose it and everything in it, and to move into a mobile home or tent. When I look at everything that's happening in our country lately, all I can think of is Ayn Rand's book The Fountainhead. It really does come down to survival of the fittest.
By the by, and off the subject, did you know that the penny will no longer be made, as it costs too much to make them for what they're worth these days?
