USPS will deliver, door to door, a letter from Nowhere, MT to Remote, GA for $0.55, even though they take a loss on it. Try to get Fedex to match that.
I’ve heard this many times. I also know quite a few places that USPS does not service.
But it is. A simple googling gives many hits confirming this simple fact. This one seemed most informative:
> The USPS actually has two legally enforced monopolies, as per Title 39 of the US Code. One is over the delivery of anything defined as a “letter,” which is within certain size and weight limits. The second is over the use of your mailbox.

> FedEx isn't trying to capture the $0.55 letter delivery market.
Because that would be illegal. Otherwise they would.
