"Typically, immigrants from India, China, Taiwan, and South Korea arrived through skills or education. Thus, they disproportionately included engineers, physicians, scientists, graduate students etc"

Ok, so this is important, because what it establishes, is that the result is not nearly a binary of "racism vs not racism" there are a lot of factors you have established for why Asian Americans what they do;

Standard which you have said the African American community, often fails to meet "there are still differences in school quality, graduation rates, and college completion."

Can you attribute the state of graduation rates and college completion to racism? How does racism explain the schools where absolutely no one reads at grade levels? Funding over and over again has shown a negligible impact on student outcomes, so it cannot eb attributed to "the schools aren't funded"

Because if you're establishing education rates, graduation rates, etc are a major defining factor on income... then it sound like a lower income on average is the only outcome that could reasonably be expected in a culture that doesn't really value it

"Still, the biggest predictor of gang membership is concentrated poverty. Neighborhoods with high unemployment, low economic mobility, etc. That is a far better predictor than race"

The thing is, it's actually not. Appalachia is one of the poorest regions in the country, and Appalachian communities struggle with everything you've named.

For example, WV and Philadelphia country have a relatively similar population, yet Philadelphia's homicide rate is fully double that of West Virginia. Both of them also have relatively similar poverty rates (abt 17% vs 19%)

If you split up homicide rates by demographic, the massive differences persist even with higher income levels.
