... Congress created the mess. Undo the prefunding requirement and the Post Office would be in the red in short order ...
You mean "be in the black" (profit).
... The prefunding requirement requires that the USPS fund its retirement accounts 75 years in advance. In other words, they have to have fully funded retirement for people who are not even born yet ...
No, it means they must pre-fund until the last current-employee-future-retiree dies.
This is a very sensible rule, and Congress should make it mandatory for every employer in the country, public & private, period.
It is an especially sensible rule for an employer for whom the handwriting has been on the wall for some time.
... The automation of the delivery routes are a significant competitive advantage for UPS and FedEx who use vehicle routing software to do things like eliminating as many left-hand turns as possible ...
Oh, for goodness' sake. The near elimination of left turns was accomplished with a guy and a flashlight and a map in the four California zip codes in which I delivered mail ... in 1981.
The early-morning parcel-only guys I see delivering SmartPost/SurePost are pretty much following the same route maps as the letter carriers.
Letter carriers are not
required to stop at a roadside mailbox if they do not have mail to deliver and the flag is not up ... that's what the flag is for.
As to USPS being saved by eCommerce, Amazon
is building-out their own network and FDX is building-out their 6th-day 7th-day service and, once the AMZN & FDX business is gone, USPS will be forced to raise its parcel rates, creating a magnificent opportunity for UPS & FDX to take away most of the USPS parcel business, once & for all.
