I agree that the parent is a beneficiary of the education, but my argument is with the fact that "customer" involves one beneficiary. By your logic for instance anyone that's childless shouldn't pay taxes for education, even though they benefit indirectly from an educated population. Isn't the company that's hiring the graduate just as much a beneficiary for instance?
