The U.S. Postal Service should not be a business
"There was no hard economic reason for hiving the Postal Service off from general government funding. Nevertheless, this division became the conceptual basis for treating the U.S. Postal Service as a market participant, same as a private business, that needs to keep its finances in the black.
Except the Postal Service wasn't really transformed into the equivalent of a market firm: It's still required to provide mail service to every corner of the country, for one thing. Its private rivals — FedEx, UPS, Amazon, etc. — are under no such obligation.
If you live out in the rural hinterlands, and providing you service isn't profitable, those companies simply don't run delivery routes out to you. Only the U.S. Postal Service does."
Our postal system is a service to our country and like in most other developed nations, shouldn't have to pay for itself any more than any other governmental agency (USDA, DOT, FEMA, military, Etc.).
