More evidence that income inequality is accelerating under Obama

The world's leading experts on income inequality, Saez and Piketty, have updated their study of income inequality in the US and have found that the top 10 per cent of earners accounted for half of all income earned in 2012, the highest level ever. Income inequality has been growing for some 30 years now. Isn't it concerning that after all that time the rate of increase is actually accelerating instead of slowing down? Isn't it also shocking that the Bush era, typically thought of as worsening inequality, may not look as bad as the Obama era?
