It's not circular. It's like this: You can burn coal in a fire, and you can make the fire bigger by adding coal. You can call that circular, but it's provably true. Kids tend to succeed if they are surrounded by success. Parents set demands, peers provide competition, etc.
As for the Jewish students... well isn't it nice that the law does not block them from moving into the better school districts? The same applies to anybody else. If you are successful, you can move into the good school district. This has been true for about 47 years in the USA. Nobody is stopping anybody.
Don't want to pay? Clearly you don't care about education, and your child would likely degrade the educational environment. Can't pay? It's pretty much the same thing, but with a small non-zero chance of being wrong, and maybe you should homeschool.

There is no perfect system. :-(
