Most people believe that inequality is rising - and indeed it has been rising for a while in a number of rich countries. And there is lots of talk and realization of this. It's harder to understand that at the same time, you can actually have global inequality going down. Technically speaking, national inequality can increase in every single country and yet global inequality can go down. And why it is going down is because very large, populous, and relatively poor countries like India and China are growing quite fast.
