Does inequality make us rich?

Economist:

America ranks as the most unequal big rich-world country (see chart). Combined with lower average incomes elsewhere, the pay of America’s top workers looks astonishing to European eyes. For comparison, it takes the equivalent of a mere $250,000 or so to enter the top 1% of two-person households in Britain.

It would be natural to conclude that high inequality is merely the flipside of America’s wealth. That is probably true to an extent. Yet America has grown more redistributive over the period examined by this special report, expanding the earned-income tax credit, a wage top-up for low earners, in the 1990s, and subsidies for health insurance in the 2010s. And it is not clear that tolerance for inequality is powering its economic outperformance over the past decade.
