Global income inequality is falling

That is the theme of my new New York Times column.  Here is one excerpt:

Income inequality has surged as a political and economic issue, but the numbers don’t show that inequality is rising from a global perspective. Yes, the problem has become more acute within most individual nations, yet income inequality for the world as a whole has been falling for most of the last 20 years. It’s a fact that hasn’t been noted often enough…

The message from groups like Occupy Wall Street has been that inequality is up and that capitalism is failing us. A more correct and nuanced message is this: Although significant economic problems remain, we have been living in equalizing times for the world — a change that has been largely for the good. That may not make for convincing sloganeering, but it’s the truth…

Many egalitarians push for policies to redistribute some income within nations, including the United States. That’s worth considering, but with a cautionary note. Such initiatives will prove more beneficial on the global level if there is more wealth to redistribute. In the United States, greater wealth would maintain the nation’s ability to invest abroad, buy foreign products, absorb immigrants and generate innovation, with significant benefit for global income and equality.

In other words, the true egalitarian should follow the economist’s inclination to seek wealth-maximizing policies, and that means worrying less about inequality within the nation.
