I think the point of the post above yours is a bit different.
A good school is one that has the best students. It is often your classmates, more than teachers, who create an environment that is conducive to learning. What seems to be the case is that rich people invest more in their kids, and their kids are simply better students. They are better behaved, with higher comprehension and math skills, and more likely to be better students. That is what creates a good school.
So it is not that schools get richer with better resources (although that too is a factor), but that richer kids with higher parental investment are fundamentally more likely to succeed. That is the real divide.
There also is the effect that the grouping matters - other things being equal, your kid will succeed more when put in a class where other students have higher parental investment, rather than when put in class with a lot of poor students having issues with absenteeism and higher incidence crime and/or substance abuse.
In essence, people are willing to pay a premium in real estate prices just so their kids would not grow in a community of kids who cannot afford this premium.
Certainly. My ultimate point was that because of the coded language, saying a "good school district" doesn't exist is, to me, equivalent to saying the problems rayiner made explicit don't exist. Just because it's a polite term doesn't mean people don't understand what it signifies, and also doesn't mean the good/bad school divide doesn't exist. I made my point poorly and wish I hadn't, as it has led to misunderstanding.
