"The wealth gap between America's high income group and everyone else has reached record high levels since the economic recovery from the Great Recession of 2007-09, with a clear trajectory of increasing wealth for the upper-income families and no wealth growth for the middle- and lower-income families." This shows the radical difference in the economy. The rerason for this might be that the upper classes have more money to make investments in stocks, companies, etc. This eventually ends with more money being given to the spender.
