“…According to a groundbreaking new working paper by Carter C. Price and Kathryn Edwards of the RAND Corporation, had the more equitable income distributions of the three decades following World War II (1945 through 1974) merely held steady, the aggregate annual income of Americans earning below the 90th percentile would have been $2.5 trillion higher in the year 2018 alone… At a recent pace of about $2.5 trillion a year, that number we estimate crossed the $50 trillion mark by early 2020.”
