Very often, proposals to even out income inequality advise one of two things: Expand people’s access to education and/or raise the top tax rates. Yet even a big increase in the share of people with a college degree would have only a minimal effect on earnings inequality, research has shown. And now it turns out that a substantial increase in the top marginal tax rate wouldn’t do any better.
