The middle class in the rich countries is where the political game is being played. They are voting in elections in the U.S., U.K., France and Germany. They are working people in the upper part of the global income distribution. They might on average be happy that the Chinese are doing well, but they are not happy that the Chinese are doing well relative to them.

Even if parties associated with right wing populism don't win, they push other parties, the centrist parties, towards their position. So they do have an influence even if they're not in power.

I was at the World Bank and a commission reviewed our work on inequality for the U.S. Congress or somebody, and the head of the commission said to us: "You are spending taxpayer money to study issues like inequality? Which goes directly against capitalism and growth." That was the perception, that it should not be studied.

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.

If, for example, each of us had the same share of capital in the national total capital, then if the share of capital goes up it's not a problem, because you get as much as I do. The problem is that capital in capitalist countries is very heavily concentrated, especially financial capital. So then if the share of income from that source goes up, that actually exacerbates inequality.

If we knew what type of jobs would exist in 20 years, we would be quite rich. But we just cannot visualize it.
