Forced school desegregation is not active for most kids. Many people buy into expensive school districts. Cupertino, Mountain View, Palo Alto, and other fine cities are not exactly desegregated. Even in more mixed areas, the school zones are seldom mixed. Then, for those without the money to isolate themselves by zip code, there is homeschooling. Kids do not get bused from one homeschooling family to another.
