While funding for parks increases head counts hand-in-hand, you have to make sure you increase personnel, both to provide good service and mentorship, but to also hopefully keep people safe. It would also help if the Park Service received multi-year funding so it wasn't subjected to the annual vaguery and hostage-taking of Congress and the Executive Branch, but that's true of any agency: there was too much destruction on NPS lands, illustrating the rectal haberdashery of unsupervised bipeds.
