What triggered the economic collapsed?

Economics 101, take it when you get a chance. Your fellow liberals insisted on banks making loans to people who couldn't afford the payments. Some of these financial institutions like Fannie Mae and Freddie Mac, who Chris Dodd and Barney Frank were in bed with, had billions of dollars of these loans and knew that the were no good. They bundled these loans as good ets and sold them to other financial institutions. You can see what happened from there. Oh yeah, the guy who was running Freddie Mac became Obama's economic adviser. No wonder the economy is in a death spiral. Schools out.
