In 2002, the U.S. Postal Service increased first-class postage rates from 34 to 37. The service had been losing money. One of the reasons is increased competition from companies such as United Parcel Service and Federal Express. Another reason is the use of faxes and e-mail, as well as electronic bill payment. With this decrease in demand for postal services, why do you think that the Postal Service is seeking a rate increase?
