[This] chart, spanning a century from 1907 to 2007, combines all the information from the charts above and tells the story of the Wealth Gap in America, a terrible economic injustice that happened from 1900 to 1930 – thirty years. The same injustice has clearly repeated itself today. The green graph measures the concentration of wealth in the hands of the few. The pink graph is the tax rate in the highest income bracket.
