Since 1970 the Post Office was detached from the Federal Govt. All of their costs of business must be paid through their services (postage, insurance, etc.)--there are no government subsidies. It is no longer a "govt service" and an extra workday simply doesn't bring them enough revenue to justify staying open on Sat. I think last year they were hammered by gas prices and fell short billions of dollars. As much as people gripe about their prices, first class mail is still much cheaper than Fedex/UPS.
