"The 2006 Economic Report of the President tells us that the real earnings of college graduates actually fell more than 5% between 2000 and 2004. " Between 1972 and 2001 the wage and salary income of Americans at the 90th percentile of the income distribution rose only 34%, or about 1% per year. But income in the 99th percentile rose 87%; income in the 99.9th percentile rose 497 percent.... the notion that it is all about returns to education suggests that nobody is to blame for rising inequality, that it is just a case of supply and demand at work.....the idea that we have a rising oligarchy is much more disturbing. It suggests that the growth of inequality may have as much to do with power relations as it does with market forces. Unfortunately, that is the real story.....Highly unequal societies also tend to be highly corrupt."
