I’d argue that amazon has stolen all the growth from shipping that could have propped up the USPS, but hey, that’s just me.

I don’t think something can be self funded and operate at a loss. I think for the former to work you can’t have the latter and vice versa.

The USPS can keep cutting services into the ground to stay afloat but eventually they’ll just collapse unless publicly funded. I think that’s ok, the service is too critical not to subsidize to a reasonable service level, it needs to be subsidized for the public good.
