USPS has a public service mandate to provide a similar level of service to communities across the country regardless of local economic conditions. In addition to daily mail delivery to far-flung locations, the Postal Service maintains post offices even in low-income urban neighborhoods and small towns that lack other basic services. The Postal Service is able to fulfill its mission while keeping postage rates low due to economies of scale.
Once the fixed costs of post offices and delivery are covered, the additional cost of new services is often minimal. If it weren’t prevented from doing so, the Postal Service could take advantage of underused capacity and build on Americans’ trust in the Postal Service to offer new services to the public while bringing needed revenue to the agency. But first we need to jettison a regulatory framework that protects private-sector rivals at the expense of consumers.
