USPS gets revenue from commercial sales, not taxation.
USPS is not immune to the entitlement mindset that plagues many large corporations such as GM.
Many large ‘private’ corporations don’t “get it”. They are often politically correct and benefit from taxpayer bailouts, funding, and regulations.
Wonder why you keep missing the point? Where does their BAIL OUT money came from? Money that is needed to keep their benefits going to their current and retired employees. They didn't plan for the future ten+ years ago with their salary and benefit packages.
That is totally false. The taxpayers will be on the hook when the USPS defaults on its loans, which they surely will, as they are billions in the red.
I notice that you also didn’t compare the USPS to a private corporation, but to GM, another disgusting and undeserving recipient of government largesse...
