> 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?
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.
