including the Congressional Budget Office, the United States has one of the highest Gini coefficients of the developed world, .42, which puts it at roughly the level of Ancient Rome. (Before taxes, the American Gini coefficient is even higher—almost .6—which is on par with deeply corrupt countries like Haiti, Namibia, and Botswana.) Moreover, the wealth gap between America’s richest and poorest families has doubled since 1989. Globally, the situation is even more extreme: several dozen extremely rich people control as much wealth as the bottom half of humanity—3.8 billion people.
