I am Asian, born in the US, and it's definitely the wealth aspect. You can only end up here in the US legally as an immigrant from Asia if you've completed some type of advance degree (or are going to do that in the US) or are extremely wealthy.
So the cream of the crop of Asia is competing against everyone of the native born population and you then obviously get this kind of disparity here.
Asians love to talk about how we focus more on education, our culture is better, blah blah. But go back to India or China and you will find lots and lots of people who don't value education and don't have much care for discipline or culture or frankly any sort of society. There's a reason India has had a Trump-like leader for multiple years and it's not because of a focus on education.
And congrats to them and their families. The stats still show that Asians who move to the US are overwhelmingly likely to be moving here to go to college, to go to graduate school, to continue their established skilled career, or with already significant assets. All of which make them usually in the top 10% (if not 1%) of their respective countries. Asians just cannot get visas to move here to work in restaurants. The only ones who can are ones who come here as refugees or in other such ways which make then the minority of Asian immigrants to the US
