The top chart shows the gap in incomes between the top 1% and the rest of us proles. The income gap reached record levels in 2006--a whopping
976 times the lower income. One of the reasons for this condition is displayed in the lower chart, a historically low top marginal tax rate. The average after tax income of plutocrats more than tripled in 2006, an increase of 256% while the average after tax income of the poorest fifth only rose 11%.
