Touché. But if you have no money, you don't pay for it every April, and can still reap the benefits. The arguments about whether this is right or wrong are plenty, but the point stands: public education is free, especially for those who have a very low income. They don't pay for it; the idea is eventually they'll pay for others' schooling in the same way others paid for theirs. That's the way I see it, at least.
