 There were early investigations of the concentration of the economic power of the U.S. finance sector, such as the Pujo Committee of the U.S. House of Representatives, which in 1912 found that control of credit in America was concentrated in the hands of a small group of Wall Street firms that were using their positions to accumulate vast economic power.When in 1911 Standard Oil was broken up as an illegal monopoly by the U.S. government, the concentration of power in the U.S. financial sector was unaltered.Key players of financial sector firms also had a seat at the table in devising the central bank of the United States.
