Yes, some demographics have it worse than others but that's a totally separate variable of the equation though. A rising tide lifts all boats. Not bettering the system because a particular group/groups will not do better relative to some other group even though both groups do better relative to their past position is foolish. This is true for systemic improvements in general, not specific to education.

How does a rising tide lift all boats when you systematically take people off the boat?

Say the education system takes an input of children with a value of 1 and outputs educated people with a "value" between 5 and 10. Even if the system is overtly racist and only outputs minorities of values 5 and 6 it is still beneficial to everyone if the system is improved so that everyone gets a +1

So you mean a system that in practice separates kids by race. Didn’t we already try that before in the South? Ever heard of Jim Crow?

Where do you think all of the funding and resources go when you do that?

Stop trying to put words in my mouth. I'm saying that the fact that a system produces unfair outcomes is not a reason to not make improvement that cause the system produce better outcomes across the board. No more, no less.

It doesn’t produce better outcomes for the people you pull out of the system then get ignored and they don’t get the resources, access, or networking opportunities they need. That’s exactly what happened during segregation.
