Actually, there are more Chinese billionaires in Shanghai than American ones in New York. So wealth is shifting, to its historical averages. Even in the Roman and Greek days, Asia controlled 75 percent of the world population and wealth, and Europe controlled about 10 percent.

I understand the angst on identity politics. In the US, it flows from the demographic possibility that non Hispanic whites will not be a majority in a few decades. If there in more intermarriage between the groups there, then this problem should solve itself.
