Inflation Adjusted Income Of All US Rose Since 1987

From Tax Foundation, "The Gains of the Top 1 Percent Don't Come at the Expense of Other Americans" by Scott A Hodge and Andrew Lundeen:

The data suggests that the incomes of all Americans are higher than they were twenty years ago after adjusting for inflation, and that everyone’s incomes tend to rise and fall with the business cycle. Between 1987 and 2010, the bottom 50 percent’s real income grew by 25 percent, middle-income Americans’ by 46 percent, and upper-middle-income Americans’ by 56 percent.

Addendum:

It turns out, I had written about the above chart in much more depth back on October 13, 2102, "Top 1 Percent Income Gain Does Not Come From Middle Class Or Any Other Americans."
