In the Wall Street Journal by Stephen Moore and Richard Vedder, The Blue-State Path to Inequality
The income gap between rich and poor tends to be wider in blue states than in red states. Our state-by-state analysis finds that the more liberal states whose policies are supposed to promote fairness have a bigger gap between higher and lower incomes than do states that have more conservative, pro-growth policies.
When politicians get fixated on closing income gaps rather than creating an overall climate conducive to prosperity, middle- and lower-income groups suffer most and income inequality rises. The past five years are a case in point. Though a raft of President Obama’s policies—such as expanding the earned-income tax credit and food stamps, and extending unemployment benefits—have been designed to more fairly distribute wealth, inequality has unambiguously risen on his watch. Those at the top have seen gains, especially from the booming stock market, while middle-class real incomes have fallen by about $1,800 since the recovery started in June 2009.
This is a reversal from the 1980s and ’90s when almost all income groups enjoyed gains. The Gini coefficient for the United States has risen in each of the last three years and was higher in 2012 (.476) than when George W. Bush left office (.469 in 2008), though Mr. Bush was denounced for economic policies, especially on taxes, that allegedly favored “the rich.”
