The Wall Street Journal reports (emphasis added):
Over the two years ending September 2010, Americans withdrew a net $311 billion — or about 1.4% of their disposable income — from their savings and investment accounts, according to the Federal Reserve. That’s a sharp divergence from the previous 57 years, during which they never made a net quarterly withdrawal. Rather, they added an average of 12% of disposable income to their holdings of financial assets — including bank accounts, money-market funds, stocks, bonds and other investments — each year.
