I think I was pretty explicit about what that means: the discrimination is more around class. My local school is one of the best in the state for example, and is ~60% "white" vs. ~80% for the local population. In fact the stats I see indicate that every racial minority group has higher representation within the student body than within the wider city. The more relevant factor is that a bunch of doctors, lawyers, engineers, etc. live in the area. There are no homes in the area for under $1M, and many are $5M+. There is no multi-family housing. 1% of the students qualify for the income-based free lunch program.
The spending per student is below average and lower than nearby worse schools, so it's not that the rich people have a higher tax base to create better schools. It's that the professional class takes for granted that of course their kids are going to take every AP class. They want their kids' friends to have that attitude too, and they expect the school to offer AP everything. If it doesn't, they won't live there.
"Buy the cheapest house in the most expensive neighborhood" is an adage here for aspirationally upwardly mobile people. So basically use your money to mix with higher classes rather than on material goods (and put your kids in school with the highest class group you are able to).

We were talking about someone who found a $575,000 home to be stretching him to his limits. Have we gotten a bit off track here?

I'm one to talk as an engineer living in a $300,000 (maybe, on a good day) home, but I technically could afford a multimillion dollar home if I found some strange reason to show off to others. Generally speaking, a $575,000 home is really a "working man's" home.
What you describe is interesting, but is it the same obvious reasons as what was brought up before? Said person isn't of the class you describe.
