Why exactly is the post office supposed to be profitable, when other government agencies that require fees for service are not? National Park Service, State Departments of Transportation, the US Forest Service, State wildlife agencies, among others, all charge fees to individuals, on top of the tax dollars they receive, in return for services. For example, the Forest Service changes grazing fees to ranchers, the Park Service charges entrance fees at almost very park, DOTs have license fees and toll roads...none are profitable and none are expected to be, so what the difference? I got into a twitter "argument/discussion" with Wrangor on this. He initially said it was because the USPS charges for the service and therefore should be profitable, then moved the goal posts and said because it was designed as a business therefore should be expected to at least pay for itself but then said it was Sunday and he was done arguing.
I sincerely want to understand why the post office is expected to pay for its self, when no other government agency or service has to do that?
