The whole point behind national parks is that corporations DON'T get to "handle" Yosemite. The biggest reason things don't "work" anymore has less to do with the expense of bureaucracy and more to do with funding.
Thirty years ago, California, then Oregon and Washington State passed property tax initiatives that limited the states ability to sustain revenue important to the running of the state. What happened is, suddenly, schools did not have the money they needed to operate. Washington (State) has never addressed this problem and a few years ago, the state legislatures were taken to task by the supreme court (our state's). Their judgement was that the state was underfunding education by 1 billion dollars a year and ordered the state to find the money.
So "some" claim that schools don't work, when what's really happening is that by cutting funding, you make it impossible for schools to operate. Class sizes get too big, schools are forced by people outside education to measure their success and the teachers are forced to teach for these tests instead of getting to actually teach.
There are many examples of people claiming something doesn't work and then they cut funding in their effort to prove it.
In the case of the Forest Service, funding has been cut so much that they can't perform the very important job of managing the forest to protect forest fires from spreading. So a few years of drought and a fire starts and now they literally have to put out the fire, when forest management could have mitigated much of the hazard.
