Just how far has the working class been left behind by the winner-take-all economy? A new analysis by the RAND Corporation examines what rising inequality has cost Americans in lost income—and the results are stunning.

A full-time worker whose taxable income is at the median—with half the population making more and half making less—now pulls in about $50,000 a year. Yet had the fruits of the nation’s economic output been shared over the past 45 years as broadly as they were from the end of World War II until the early 1970s, that worker would instead be making $92,000 to $102,000. (The exact figures vary slightly depending on how inflation is calculated.)
