If you look at the post-war period, from 1946 till 1970s/early 1980s, the US has a much more progressive tax rate, and there was more bank regulation. It was also coincidentally the golden age of American economics. Since the 1980's, taxes have become more and more regressive and regulation on all fronts against corporate excess and distortion of markets has increased. Government has a very important role in capitalism (bust monopolies, ensure companies compete fairly etc). Since 1980's there have been steadily greater and greater economic crises. Many would argue that capitalism has been corrupted through a corruption of politics.
