California is not like the rest of the US. The racial dynamics are different, and immigrant families from poorer backgrounds are fine paying extremely high premiums or even rent out a garage to live within in order to send their kids to top school districts. "American" families don't do that.
On top of that, utilizing public services is viewed negatively in the American naturalization process, as it can be contested that an applicant is at risk of becoming a "public charge".
Additionally, the moment a neighborhood becomes too "Asian" or "Latino" in the Bay, all the White and Black families who can afford to end up leaving, and those who remain complain about us "changing the character" of our neighborhoods or "being too competitive".
The Western US (Dallas westwards) has an entirely different racial and ethnic dynamic from the rest of the US.
