Dept. of inefficient government monopolies

USPS:

The Governors of the U.S. Postal Service have approved new prices for mailing services, including a 2-cent increase in the price of a First-Class Mail stamp to 44 cents. Prices for mailing services are reviewed annually and adjusted each May. The new prices will go into effect Monday, May 11.

Perry notes:

If stamp prices had increased over time at "only" the rate of gas prices, a first-class stamp would only cost only 17 cents today instead of 44 cents. If stamp prices had increased at the same rate as consumer prices in general, stamps today would cost about 25 cents.

When gas prices rose last summer, Rep. Bart Stupak (D.-MI) introduced "The Federal Price Gouging Prevention Act," which would make it a crime to "sell crude oil or gasoline at a price that is unconscionably excessive." Shouldn't we now investigate "unconscionably excessive stamp prices" of the postal monopoly?

The only reason the United States Postal Service can price gouge like this is because federal law prohibits competing delivery services like UPS and FedEx from delivering regular mail.
