I don't think segregation is the model, but merely a subfactor. Segregation can be insidious, but it can't explain why getting a huge cash infusion doesn't work, especially since segregation arguments are often about unfair funding differences. But $200M ($100M from Zuckerberg) is a shit-ton of money to get. It's like saying if there were more white and Asian kids there, then money would be spent more wisely.

Given the information from the article, I think power play between major actors better explains how so much money vaporized. I mean, how did consultants get $20M? Because of racial distribution? I think it's because of power play dynamics.

I think tax revenue will be better spent because the flow is predictable, but when you get a sudden cash infusion with no plan, then you won't spend it as well as well-budgeted tax revenue. Perhaps it is also partially Zuckerberg's fault, because he should've realized the political fighting and released the money incrementally.
