From what I read, poor and average immigrants do great, even African ones. Even more so, the first generation born in the US.
My greater point doesn't negate the impact of past treatment. If anything, it's strongly supports it. What I think it adds to the conversation is the idea that the challenge is very different than overly simplistic model of skin color discrimination which most people around usually try to reduce everything to.
Miss attribution of the root cause leads to ineffective Solutions.
I agree that historic impacts can be scoped into the definition of systemic racism, but that doesn't mean that other tenants of systemic racism are not overstated or incorrect.
It is a matter of what the hypothesis being tested is. If your hypothesis is that racial inequality is due to ongoing discrimination on the basis of skin color, finding that the cause is a difference in potential undermines that hypothesis.
If the difference in outcome is due to different potentials, not skin color, you can ask why are the potentials different.
I think this is the interesting and most relevant question.
Why are outcomes so different for a black person born dirt poor in the US with immigrant parents compared to a black person born dirt poor with slave ancestors?
This Cuts directly to the heart of why racial inequality is so persistent in the United States.
Another question is what are people owed if someone's ancestors were under artificial selection by slavers for many generations?
I think a claim there may be legit. However I'd rather keep objective admissions and hiring and just give cash transfers. I can understand though that people want status as well as cash
And yes, biases of past treatment is one of the main issues that many are trying to correct with affirmative action-like programs. There doesn't have to be any modern, active racism at all to try and correct the terrible damage done in the past on a systemic basis. In many cases, this past injustice is exactly what systemic racism is referring to.
