The Postal Reorganization Act requires the Postal Rate Commission to consider only lawful postal costs in its determination of what postage rates may be and they didn't allow USPS To claim that cost.
They've been paying the $5 billion since FY 2007 ~ and it has been exceedingly destructive of sound financial management.
At the same time, as you saw in the Senate vote, Congress will not allow USPS to shed unnecessary operating costs.
It may well be time to start burning down useless post offices ~ since the law does allow USPS to not reopen a post office that burns down.
Regarding insolvency, they continue to be a government agency ~ and even if 'Bailed Out' they'd still run a smaller deficit than Commerce, State, Defense, Energy, Education, Human Resources, .........
USPS is obsolete. Also, I don’t care if the other Departments run larger deficits—it doesn’t change the fact that USPS is running in the red!
Time for USPS to be eliminated and so-called “First Class” mail delivery to be opened up to the private sector.
I can tell you that as a business owner I *never* trust critical documents to the USPS. I’ve never had a Fedex failure, but I have had too many thefts, delivery failures, etc. with USPS to count.
