Someone please correct me if I am wrong. Being a tax payer has nothing to do with the post office. They are controlled by congress but use no government moneys.
I believe you would find that all delivery services (UPS, FedEX, etc) use a hub approach of some type.
You are correct, at least for the time being. Eventually however if Congress refuses to let the Postal Service make changes to stop the red ink, I imagine we taxpayers will be asked to bail them out. No agency or company can run billions in red ink every year indefinitely.
I was planning to mention that the issue Scott brought up in his first post isn't unique to the USPS. I've had plenty of packages delivered by UPS and FedEx that went through equally circuitous routes before they got to my door. It is just like the airliine hub business model, where you have to fly 400 miles north to catch a plane to fly you 800 miles south.
All the various shipping companies will be happy to cut out all the extra miles if you want to pay 4 times what the package is worth for next day delivery. I've often assumed this is part of the reason they let their normal ground shipping packages sit around or take side trips; if they can aggravate you enough maybe you will spring for the super duper next day shipping on your next purchase.
My new "favorite" shipping method involves all three of the major shippers. UPS or FedEx picks up the package and ships it to a large regional postal hub, where the USPS takes over and has the mail carriers handle the actual delivery to the consumer. Watching the online tracking info on one of those shipments is mind boggling.
