> why would you go to grade school and high school at institutions that produce graduates like that?
Do you not know how U.S. K-12 public schools are funded by local property taxes, which means the quality of a child's education is a direct causal relationship of the wealth of their neighborhood?
Why don't these children just grow up in richer neighborhoods?
The quality of an education isn't proportional to the amount of money spent; learning is remarkably cheap if a school wants to focus on outcomes. There's a bit of give in where the teacher sits on the bumpkin-genius scale (although even then, the range of salaries isn't that wide in the big picture).
Although forcing the funding to go through a collective rather than letting people choose a school and pay on in individual basis would probably deliver a pretty serious blow to the quality.
Most are overpaying in taxes for what they are getting.
Not to mention single/families without kids and seniors that still pay for school districts.

Do you not know that the US is a Federal system and there are (at minimum) 50 different ways that schools are funded?
California's schools (for instance) aren't funded by local taxes, they're funded by the state and allocated funding based on a formula[1] of performance, need, population, etc. They can be augmented by local taxes, but in practice that's rare as the wealthy just avoid the system altogether; instead, opting for private institutions.
That's at least 12% of the population that is not funded in the manner you outline.
