There is a recent study by Saez and Zucman showing, with new data which I didn't have at the time of the book, that wealth concentration in the U.S. has risen even more than what I report.
Nedavna studija Saeza i Zucmana pokazuje, uključujući nove podatke kojima ja nisam raspolagao  dok sam pisao knjigu, da je koncentracija bogatstva  u SAD-u porasla i više no što ja u knjizi tvrdim.
