Occupation: Chairman, president and CEO of JPMorgan Chase
Despite being at the helm of one of the much despised too-big-to-fail banks, Dimon's clout has only grown since the 2008 financial crisis. JPMorgan Chase has the healthiest balance sheet among the big banks, as shown by the firm's performance in the Federal Reserve's recent stress tests of them. Dimon has used his stature to vocally protest increased regulation of the financial sector. He even went so far as to call recently proposed international banking regulations "un-American."
