No?

there might be an argument for it since DeJoy has been trying to run it like amazon ruining rural service

Yes, USPS is run as a financially self-sustaining business wholly owned by the federal government.

For a long time it was in this weird double bind because the federal government mandated generous health insurance for USPS employees, but did not allocate funds for it, because USPS was supposed to provide its own funds to cover all expenses, but it looks like new legislation (PSRA) was passed in 2022 to move the healthcare coverage burden from USPS and onto the OPM.

So, combining that other thread about Canadian payments, USPS is (the American equivalent of) a crown corporation?

It is not. It is not taxpayer funded, and is thus organized similarly to a company since all funding comes from postage, but it's an independent US government agency.

It wasn't intended to be profitable. It was intended to provide a public service in the national interest. Any funds raised through postage were to hopefully offset the considerable costs, but the considerable costs were in and of themselves seen as a necessary expenditure for a critical responsibility of the federal government, no more or less so than the considerable costs associated with the raising of armies and navies for the defense of the nation.

No??? It's an independent bit of the exec branch designed to operate as a public service. You should have learned this in high school civics class

Amazingly, I'm not American!

Anyway it was just a silly joke about how your postal system is state owned but (sometimes) expected to make a lot of money, rather than run at a loss like a normal public service.
