that is pretty entertaining and rings true for me 20 years ago. I have found them to be better since competing with fed ex. maybe I have been lucky local with post offices in san diego. I probably only go there once a month.
It's basically the same scenario in every large public sector entity with enormous legacy costs. There is just no possible way to generate enough growth to pay for the legacy benefits. Meanwhile, the taxpayer and the consumer (oftentimes with little alternative due to their monopoly nature) are burdened with the futile attempt of "saving" these organizations.
same situation at many DMV's, courthouses, social security offices, etc, etc...hordes of people waiting, hordes of employees standing around doing alot of nothing...
