It should be able to sustain itself and still provide courteous service. USPS is a failure in customer service and competence and there is no justification for that. FYI we already foot the bill for their incompetence. And yes, there is tax money that goes to them even though they do create some of their budget by sales. No private business that ran like USPS would still be in business.Yes, but it should not be taken advantage of by private business or else it'll become a major loss center and us the tax payers will have to foot the bill, in addition to what we are already paying.
