The USPS will take a envelope to virtually any address in the United States for $0.50, cheaper for bulk rates. Will UPS or FedEx do that?
the govt does it cheaper and better.
as usual.
Last year the USPS reported a 2.7 billion dollar loss. I guess that falls into the category of going in dept to give out things for free (nearly free) for people that still write checks to pay bills and mail letters (see Grandma example above). They simply cannot compete with the private companies that do over night delivery, delivery that comes with a guarantee.
