Devin Leonard:

The USPS is a wondrous American creation. Six days a week it delivers an average of 563 million pieces of mail—40 percent of the entire world’s volume. For the price of a 44¢ stamp, you can mail a letter anywhere within the nation’s borders. The service will carry it by pack mule to the Havasupai Indian reservation at the bottom of the Grand Canyon. Mailmen on snowmobiles take it to the wilds of Alaska. If your recipient can no longer be found, the USPS will return it at no extra charge. It may be the greatest bargain on earth.

I love the USPS but they have been in trouble for a long time. It makes no sense to charge so little for such a enormous offering — I say it a lot, but they really must charge more.
