What is different between national inequality and global inequality is you have another element there that is sometimes forgotten: what matters for global inequality is relative growth rates between poor and rich countries.

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.

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.

People in the rich countries who have done very well, who are at the top of the income pyramid, try to steamroll over the opposition of the middle without changing anything in social programs, or any redistribution. And they take their votes for a given. They have rich people that bankroll them. And the globalization would continue, but it would continue with permanent dissatisfaction among large segments of the people.

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.

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.
