I homeschooled my daughter for reasons other than culture wars or politics (she’s a violinist and public schools didn’t regard practice time as particularly important.)

But I never thought of public school funding as transactional. We did not take direct advantage of the benefit; but a reasonably well educated populace benefits me in a host of other ways. So I harboured no resentment when paying my public school levy.
