USPS

[Drucker]

The Postal Service is a lot of things but The USPS has not directly received taxpayer-dollars since the early 1980s with the minor exception of subsidies for costs associated with the disabled and overseas voters

And to beat the drum some more, the USPS delivers over 200bllion items year, compared to UPS 4billion and Fedx 1.5billion.
So rag on them all you want
