The thing they're trying to combat is people claiming residency in a better school district. We had a case here where the parents were driving their kid to grandma's so the kid could go to school there instead of in a bad local school.
So what? Grandma's paying taxes there.
Real solution is to loosen regulations on private schools and provide equivalent tax return to parents who choose private over public.
she owns and pays for a home in the school district. the school knows and admits this.
if she didnt, i would (sort of) agree. but she does.
