During World War I, Americans were exhorted to buy Liberty Bonds to help their soldiers on the front. Now, it seems, they will be asked to come to the aid of their banks - with the added inducement of possibly making some money for themselves. As part of its sweeping plan to purge banks of troublesome assets, the Obama administration is encouraging several large investment companies to create the financial-crisis equivalent of war bonds: bailout funds. The idea is that these investments, akin to mutual funds that buy stocks and bonds, would give ordinary Americans a chance to profit from the bailouts that are being financed by their tax dollars. But there is another, deeply political motivation as well: to quiet accusations that all of these giant bailouts will benefit only Wall Street plutocrats. If, as some analysts suspect, the banks' assets are worth even less than believed, the funds' investors could suffer significant losses. Nonetheless, the administration and executives in the financial industry are pushing to establish the investment funds, in part to counter swelling hostility against the financial industry. The embrace of smaller investors underscores the concern in Washington and on Wall Street that Americans' anger could imperil further efforts to stimulate the economy with vast amounts of government spending. Many Americans say they believe the bailout programs ... will benefit only a golden few, including some of the institutions that helped push the economy to the brink. Critics like Joseph E. Stiglitz, a Nobel Prize-winning economist, argue that the bailouts merely privatize profits and socialize losses.
