The Bush Economy - WSJ.com: "By pushing all of this excess credit into the economy, the Fed created a housing and mortgage mania that Wall Street was only too happy to be part of. Yes, many on the Street abandoned their normal risk standards. But they were goaded by an enormous subsidy for debt. Wall Street did get 'drunk' but Washington had set up the open bar.
For that matter, most everyone else was also drinking the free booze: from homebuyers who put nothing down for a loan, to a White House that bragged about record home ownership, to the Democrats who promoted and protected Fannie Mae and Freddie Mac. (Those two companies helped turbocharge the mania by using a taxpayer subsidy to attract trillions of dollars of foreign capital into U.S. housing.) No one wanted the party to end, though sooner or later it had to."
