Their comment was on people moving from traditional nomadic life to modern education within a lifetime. How are Asian Americans relevant to that situation in the slightest? Because both groups of people happen to be Asian?

You just witnessed modern US propaganda in action. We are all constantly barraged by messages about "if you look non-white you must be oppressed, poor thing". And because it is constant it is making people perform snap judgements rather than actually think.

Of course someone from Uzbekistan is quite different from an an American with a vaguely Asian looking face, both culturally and economically. Any yet the parent comment author's brain automatically filed them in the same bucket. This kind of automatic thinking is exactly how propaganda works.

I'm struggling here. Are you saying that there aren't any barriers for entry in the US? For everyone, or for Asians specifically?

Ironically some Asian Americans were interned in concentration camps in living memory. George Takei, for example.
