Here's the problem: you cannot guarantee equal outcomes across intersectional groups. Period. Not going to happen. A hundred years of psychometric research backs this up; there are simply differences that cannot be papered over by adjusting metrics and applying equalizing coefficients.

A highly effective education system that really gets the best out of every person involved is also going to be selective, it is going to group people into different classes based on ability, and the resulting output is going to be highly offensive to the militant people who right now are literally doing their best to take over American cities.

So no, we can't fix this problem. We can spend more on it, but ultimately all of that money is just IOUs against a decaying system that demands everyone be equal, even if that lowest common denominator means all but the super-rich end up living in a favela within a few decades.
