You're out of your element here. I'd suggest you move to the General forum and post on things like gardening and what song you're listening to. In the mean time, you can educate yourself. Here, I'll even give you your first reading assignment.

You can thank me later.
It's too simplistic to explain the Housing Bubble. I'm not disputing anything in the link that you provided and I'm not saying that subprime loans weren't a problem. I'm only pointing out that the Housing Bubble appears to be a much larger problem, pretty much destroying the housing market for everybody - subprime or not.
