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
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.
