I think its easy to nitpick the flaws of western melting pot societies while ignoring that many asian societies are not remotely melting pots and citizenship is near impossible to get. The number of immigrants from Asia to the states shows that there's something desirable about its culture. How many Americans move to China or Japan and attain citizenship? Not many. Its seen as best as a temporary work gig dues to the complete lack of acceptance of foreigners and ethnocentrism there.

> citizenship is near impossible to get

The requirements for naturalizing as a Japanese citizen are actually quite reasonable both in paper and practice.

I did not even talk about the flaws the West has. It is about majority and minority. There is always a disadvantage for minority, especially psychologically. You just love to jump to conclusion that Western culture is better and other cultures are worse and find the evidence to serve your goal.
