I kick in to pay for fire police and roads. Everyone does and benefits.
Schools are different, I pay for me and mine. Other parents should pay for theirs. Perhaps the childless should kick in for the social benefit.
Actually we're talking about Star Parker's article where she claims it's about values and not economics. You've made it clear that the deciding factor on whether to out of public schools and into religious schools, where they can learn values that sustain life is economic. You'll send them to a school that teaches your values only if the government makes it worth your while.
