If one read the September 6 edition of Newsweek, the "Obama's Old  Deal" article, by Micheal Hirsh, may explain why Barack Obama, although the president of the United States, is not a leader. He was actually surprised that the banks after having their bacon saved went back to their old ways:

Barack Obama was “incredulous” at what he was hearing, said one of his top economic advisers. The president had spent his first year in office overseeing the biggest government bailout of the financial industry in American history. Together with Federal Reserve chairman Ben Bernanke, he had kept Wall Street afloat on a trillion-dollar tide of taxpayer money. But the banks were barely lending, and the economy was still mired in high unemployment. And now, in December 2009, the holiday news had started to filter out of the canyons of lower Manhattan: Wall Street’s year-end bonuses would actually be larger in 2009 than they had been in 2007, the year prior to the catastrophe. “Wait, let me get this straight,” Obama said at a White House meeting that December. “These guys are reserving record bonuses because they’re profitable, and they’re profitable only because we rescued them.” It was as if nothing had changed. Even after a Depression-size crash, the banks were not altering their behavior. The president was being perceived, more and more, as a man on the wrong side of an incendiary issue.
