You raise a very important point and one that is difficult to discuss.
I'm Asian and I grew up with parents who hewed rather closely to Asian culture. There are two values they championed essentially above all others, well known to most: devotion to family and the intense pursuit of academic achievement. I do feel like I've been a direct beneficiary of that cultural impulse. Much like yourself, I did my best to leverage educational opportunities and had the stability of a supportive family.
When we talk about culture and the Black community, many people become understandably wary. It's a fine line between invoking culture and being seen to blame Black people for their own problems. Not to mention that, in doing so, it can be easy to lose sight of the richness of Black culture and its extensive contributions to so many aspects of the American experience e.g. in music, sports, entertainment, art, literature, and cuisine.
Perhaps a better way to frame it is that when a particular community has suffered so much injustice and attendant compounded stagnation, it's very hard to find an expedient solution to bring that community to parity that doesn't involve constructing fresh and even revolutionary internal narratives around achievement (and not just academic). Without that sort of effort, it might take many more generations for a combination of government intervention and the natural course of progress to fully remedy the imbalance.
And there's also the problem of exacerbating racial animus in the course of addressing that imbalance.
While I understand the need for it intellectually, I have substantial misgivings about preferential treatment being extended specifically to Black (or Hispanic or Native American) people along racial lines. There is something that feels deeply wrong about attempting to cure racial injustice by inflicting new racial injustices on people whose only fault was being born a particular race at the wrong moment in history, especially when we are purporting to be an enlightened society that has learned its lesson in this regard.
The position is unpopular with many here, but it is my opinion that we should not be devising a society that argues that a boy from an underprivileged neighborhood in Philadelphia is more deserving of opportunity than a girl from a disenfranchised part of the Rust Belt because he's Black and she's White. Rather, we should be saying that they are nearly equally in need of help from society because they are both disadvantaged. While this is not perfectly fair insofar as it does not factor in race, I believe it is a policy position that on balance would help the Black people who are most in need of it without leaving anyone of another race feeling as if (s)he's experiencing undue discrimination.
Unfortunately I believe that quandary is even more fraught than the issue of police killings and therefore at present resistant to the possibility of honest discourse.
