Stop The Presses, Wait, Nothing to See Here, It's the One Percent, Damnit

 Yeah, about Obama's inequality argument -- seems it was never there to begin with:
But it’s just not true, according to a new study in National Tax Journal from researchers at Cornell University. (Here’s an earlier, working-paper version.) The academics, led by economist Richard Burkhauser, don’t say the findings of Piketty and Saez are wrong — just incredibly, massively incomplete. According to the Cornell study, median household income – properly measured – rose 36.7%, not 3.2% like Piketty and Saez argue. That’s a big miss.
And all income levels got richer. Yes, the very rich did exceptionally well, mostly due to technology and globalization. Incomes rose 63% for the top 5%, 56% for the top 10% and 52.6% for the top 20%.  But everyone else made out pretty well, too. Incomes rose 40.4% for households between the 60th and 80th percentiles, 36.9% for the next quintile, 25.0% for the next, and 26.4% for the bottom 20%. There’s the “shared prosperity” Obama says he wants, right in front of his eyes. (Indeed, the study finds, income inequality has actually been shrinking since 1989, with the Gini index falling to 0.362 from 0.372.)
As the Cornell study concludes:
Income inequality increased in the United States not because the rich got richer, the poor got poorer and the middle class stagnated, but because the rich got richer at a faster rate than the middle and poorer quintiles and this mostly occurred in the 1980s. .. the apparent failure of the median American to benefit from economic growth can largely be explained by the use of an income measure for this purpose which does not fully capture what is actually happening to the resources available to middle class individuals.
See, Piketty and Saez made lots of odd choices about what to measure and how to measure it. They chose to measure something called “tax units” rather than households, a move which ignores the statistical impact —  including economies of scale — of couples who cohabitate, kids who move back in with their parents after college, and senior parents who live with their adult children.
They chose to ignore the value of all government transfers — including welfare, Social Security, and other government provided cash assistance — received by the household.
They chose to ignore the role of taxes and tax credits.
They chose to ignore the value of healthcare benefits. In short, Piketty and Saez ignored a lot of stuff. Again, Burkhauser and his team;
 The apparent failure of the median American to benefit from economic growth can largely be explained by the use of an income measure for this purpose which does not fully capture what is actually happening to the resources available to middle class individuals …  When using the most restrictive income definition – pre-tax, pre-transfer tax unit cash (market) income—the resources available to the middle class have stagnated over the past three business cycles. In contrast, once broadening the income definition to post-tax, post-transfer size-adjusted household cash income, middle class Americans are found to have made substantial gains.
So the tax and regulatory polices of the past three decades did not lead to stagnation for the middle class at the hands of the rapacious rich. Claims to the contrary — such as those made by Obama, the Occupy movement, and many liberal economists — never really passed the sniff test of anyone who lived through the past few decades. And now we know why: The inequality and stagnation alarmists were wrong. And so, therefore, is the economic rationale of the president’s class-warfare economic policies. Not that economics ever had much to do with them anyway.
