It is one of the few constitutionally authorized functions of government.
I would eliminate SS and 40 other government agencies before eliminating the Post Office.
the problem isn’t the idea of a Post Office.
it’s the huge payroll and pension costs.
it’s the unionized workers who “negotiate” with people they give donations to. clear conflict of interest.
there’s lots of smart hardworking Americans who’d do those jobs as well or better, for half the money.
