Global inequality is such an abstract concept, simply because there is no global government. Telling people in rich countries who have had no increase in real incomes, stagnant median wages and so on, that on the other hand global inequality is going down because people who are much poorer than them are getting richer - it's something that maybe they would like in an abstract sense, because everyone is happy there are fewer poor Chinese, but you may not be as happy if these Chinese are taking your job.

In the U.S. when people like me started writing things about inequality, the economic journals had no classification for inequality. I couldn't find where to submit my inequality papers because there was no such topic. There was welfare, there was health issues, there was trade obviously. Finance had hundreds of sub groups.

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

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.

While you can say that the problem of the middle class in the rich countries is too much globalization, the problem of the people who are very poor is really that they are not included in globalization. For them, the success of their own countries at becoming part of this international division of labor would be good news.

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.

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.
