Not according to members of Congress from rural districts, union representatives, and lobbyists for magazine publishers, bulk mailers, and greeting card companies. They contend that the Postal Service needs volume to make money, and that curtailing service will only encourage mailers to take their business elsewhere and accelerate the USPS's decline. "Eliminating Saturday mail delivery is not a solution," said Sen. Jerry Moran (R-Kan.). "Smart reforms are needed to make sure the Postal Service can compete in a digital world, increase revenue, and not become a taxpayer liability." Among the steps the post office could take, he and other critics say, is capitalizing on the data and patents it holds. An internal report in 2011 found that the Postal Service was leaving $500 million a year on the table because it "does not manage its portfolio of patents to maximize commercial significance." The USPS also gets virtually no revenue for its valuable ZIP codes for the nation, which it sells to businesses for $60. Some advocate letting the nation's 32,000 post offices serve as branches of a massive postal savings bank, generating revenue and serving the needs of millions of "unbanked" Americans.
