If our taxes go to things like National Parks, why do we still have to pay an entry fee when we go in many of them?

And, they're pretty expensive!

Because your taxes aren't enough, and user-fees are a way to limit the costs for those that don't use the service and put the majority of the burden on those that do. When it's a school or something the idea is usually that even poor people should have schooling for their kids so user-fees are a bad idea, especially considering there's a cost for schooling kids in terms of supplies and the like, so more fees on top of that is just unacceptable.

National Parks? Visiting one is a luxury no matter how you slice it.
