Income Inequality

From Jared Bernstein:

Back in 1979, the average income of the top 1% was about 33 times that of the bottom fifth.  In 2007, that ratio had grown to 100.  The real income of middle-class households grew 19% over these years, less than 1% per year, while that of the top 5% grew by about 150% and the top 1%, by 240%.
