Well, there's no such thing as a tax cut, only a services cut, because cutting taxes results in cutting services. If the money isn't there and you want the same level of service (and the required funding for that level of service) fees are the only way to go if the population wants fewer and fewer taxes.
Right now the 5 dollar a day (30 dollar per year) parking fee in the Angeles National forest goes for paying the rangers to pick up trash and small maintenance. The Dept. of Agriculture apparently doesn't have enough money to pay for this themselves.
I'm not for or against tax cuts. But if the money isn't there in the public coffers, private fees will be used to make up the difference. It's a public policy choice.
