Incompetence or malfeasance?

For awhile there I wasn't sure whether it was simply gross incompetence or deliberate malfeasance, but I've now reached the conclusion that Bush and his henchmen are deliberately trying irredeemably to destroy the U.S. economy in order to spite Obama. Like Humpty Dumpty, all the king's horses and all the king's men won't be able to put it back together again.
