@hawkeye10,
I agree with hawkeye here; they're all at fault. They "all" have the fiduciary responsibility to protect its citizens from this kind of uncontrolled freedom to gamble on the security of our country. They were asleep at the switch. It's our fault to letting our government representatives become the "yes" men to lobbyists rather than the representatives of the people, because we kept voting in the same people.
BTW, many thought Greenspan was god; I never did. His playing with the interest rates never impressed me; not one iota.
