It's Now Official: Bush Has Katrina-ized the US Economy.

Former Federal Reserve Chief Alan Greenspan says the U.S. economy is in the worst shape in 60 years:

"The current financial crisis in the US is likely to be judged in retrospect as the most wrenching since the end of the Second World War," Greenspan said in a Financial Times commentary.

"It will end eventually when home prices stabilise and with them the value of equity in homes supporting troubled mortgage securities," he said, referring to the meltdown in the US sub-prime home loan market and subsequent massive losses for the banks holding the debt instruments.

"The crisis will leave many casualties," he said, his remarks coming after Bear Stearns, the fifth largest US investment house collapsed Friday and was taken over by JP Morgan Chase for a fraction of its value of only a week ago.

"I want to thank you, Mr. Secretary, for working over the weekend," Bush said as he met with his economic advisors at the White House. "You've shown the country and the world that the United States is on top of the situation."

Actually, many analysts and critics said, by focusing on Paulson's working hours instead of on the fear gripping Main Street and Wall Street, the president seemed to show just the opposite -- that he has failed to grasp the gravity of the country's economic crisis.
