For example, Hillary outspent Trump 2:1, yet still lost.
These are National Parks, not state parks. Locals don't pay for them, we all do.
Usually these fees are for multiple days. For Yosemite: car fee is valid for a week(there are other deals if you want to stay for longer or visit multiple times an year). The wilderness permit... I don't really know. You do have to submit start and end dates for each trip, but the fee covers the duration.
EDIT:
Also Yosemite: it appears that foot traffic is charged too. https://www.nps.gov/yose/planyourvisit/fees.htm
That highly depends on the park.
We really need to include suggestions for adding programs and laws for encouraging saving, removing predatory lending, and incentivizing responsible spending in articles like these. There is too much focus on consumer spending and not enough on household stability and having money in the bank for emergencies.
