Consider incomes for the average U.S. household. They ticked up 0.7 percent from 2008 to 2014, after taking inflation into account. But even that scant increase reflected mainly the rise in income for the richest tenth of households, which pulled up the average. For most others, incomes actually decreased — as much as 6 percent for the bottom 20 percent, at a time when the economy was mostly recovering.
Or consider employment. The U.S. economy has added a healthy average of roughly 200,000 jobs a month since 2011. Yet most have been either high-paying or low-paying positions. By the end of 2015, the nation still had fewer middle-income jobs than it did before the recession, according to the Georgetown University Center on Education and the Workforce.
