I’m (mostly) white. The first 5 years of my life I grew up in a trailer house. My wife is also (mostly) white, and both sides of her family lost everything during the Great Depression. Is there any good reason a rich black kid should have been out ahead of us in admissions, just because of his skin color?
That shouldn't ever be a goal.
Unfortunately a lot of people don't realise that the real world isn't, and can't be, that way.
Is it income disparity? Single parent households? Lack of funding for schools in poor communities? Why can't we focus on addressing those and leveling the playing field rather than picking one way to group people (by race in this case) and artificially tipping the scale? Why not by gender, or family income, or height or beauty? Those all have impacts to life outcome too.
And the bottom half, most of those aren't the kind of shitty parents you're suggesting they are, either.
