Public education does not exist for the benefit of students or the benefit of their parents. It exists for the benefit of the social order.

We have discovered as a species that it is useful to have an educated population. You do not need to be a student or have a child who is a student to benefit from public education. Every second of every day of your life, you benefit from public education.

So let me explain why I like to pay taxes for schools, even though I don't personally have a kid in school: It's because I don't like living in a country with a bunch of stupid people.
