One answer: it's a natural monopoly (which means it has huge economies of scale.) A second competitor would need to make enormous investments to duplicate the USPS' infrastructure.
Second answer: it's because of regulation. It's against the law to go into business delivering mail. This prevents new entrants from showing up and taking share away from the USPS.
Third answer: It's because it LOSES MONEY. No startup in their right mind could compete with the USPS based on $0.42 to mail a letter.

The price of a US postal service postcard stamp is 27 cents.
There are many legal monopolies. The United States Postal Service is the only letter mail provider and is government funded to make it run at a loss.
A traditional monopoly can be considered whenever a single company controls the vast majority of an industry. In 1984 the US Federal Government split up AT&T due to the corporation having a monopoly on the telephone service industry.
Whenever the US Postal Service thinks it is losing money. The increases are usually 2 cents though, and seem to occur every couple years.

How do you become a contractor for the US postal service?
Yes. We are an American territory and American citizens. We do have the US Postal Service and the postal rates are the same as they are in the continental US.
The Postal Service, like the US Government, is self-insuring.

US Postal Service
"The US Postal Service currently employs thousands of men and women as letter carriers." You would use "US Postal Service" as if it were the name of a company, and mail carriers, post office clerks, etc. are employees of that company. For all intents and purposes, you can think of the US Postal Service as being like a company that is owned by the US government.
