Joseph Stiglitz, a Nobel Prize winner, writes about growing inequalities in richer countries: Inequality Is a Choice.
A quote: "Excessive financialization — which helps explain Britain’s dubious status as the second-most-unequal country, after the United States, among the world’s most advanced economies — also helps explain the soaring inequality. In many countries, weak corporate governance and eroding social cohesion have led to increasing gaps between the pay of chief executives and that of ordinary workers — not yet approaching the 500-to-1 level for America’s biggest companies (as estimated by the International Labor Organization) but still greater than pre-recession levels. (Japan, which has curbed executive pay, is a notable exception.) American innovations in rent-seeking — enriching oneself not by making the size of the economic pie bigger but by manipulating the system to seize a larger slice — have gone global."
