Doomsday for the Greenback

""We are so utterly dependent on the 'charity of strangers' (foreign investment) that a 9% blip in the Chinese stock market (or even a .25 basis point up-tick in the yen) sends Wall Street into a downward spiral. As the housing market continues to unwind, the stock market (which is loaded with collateralized mortgage debt) will naturally edge lower and foreign investment in US Treasuries and securities will dry up. That?ll be doomsday for the greenback as central banks across the planet will try to unload their stockpiles of dollars for gold or foreign currencies.""
