The optimal society is like Silicon Valley. It is 1/3rd White, 1/3rd Chinese, and 1/3rd Indian. It has a GDP per capita of $500K, and every single important invention since 1960 was made here.

I am Danish, and I want to import 5 million >110iq Indians, and 5 million Chinese for this reason. We would be a superpower within decades. Euro-Sino-Indo collaboration is the future.
