EW paper by Emmanuel Saez of the University of California, Berkeley, and Gabriel Zucman of the London School of Economics suggests that, in America at least, inequality in wealth is approaching record levels. The authors examine the share of total wealth held by the bottom 90% of families relative to those at the very top. In the late 1920s the bottom 90% held just 16% of America’s wealth—considerably less than that held by the top 0.1%, which controlled a quarter of total wealth just before the crash of 1929. From the beginning of the Depression until well after the end of the second world war, the middle class’s share of total wealth rose steadily, thanks to collapsing wealth among richer households, broader equity ownership, middle-class income growth and rising rates of home-ownership. From the early 1980s, however, these trends have reversed. The top 0.1% (consisting of 160,000 families worth $73m on average) hold 22% of America’s wealth, just shy of the 1929 peak—and almost the same share as the bottom 90% of the population.
