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 finding comes from a recent investigation by Christoph Lakner, a consultant at the World Bank, and Branko Milanovic, senior scholar at the Luxembourg Income Study Center. And while such a framing may sound startling at first, it should be intuitive upon reflection. The economic surges of China, India and some other nations have been among the most egalitarian developments in history.
