In 2009, the US Postal Service increased first-class postage rates from 42 cents to 44 cents. 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 the Postal Service is seeking a rate increase?
