One thing I see few people discuss in terms of Asian and affirmative action, is that the immigration system overwhelmingly selects the wealthy, smart or other desirable qualities for all immigrants. And due to historical reasons like Chinese Exclusion Act, majority Asians in America had to go through those filters, or their parents had to.

Of course those people are going to succeed more than the average Americans who did not have to go through those filters, somehow being subject to harder selection became an unfair advantage?

You know the easiest way to bring down the average achievement of Asians? Invite a bunch of poor, uneducated, unmotivated Asians to become US citizens, soon those new arrivals will drag down the averages, making Asians into whichever socio-economic group you want.
