Structural changes are required for then USPS to be financially stable. Chief among them is modifying the Universal Service Obligation (USO).

For far too long, private shipping/logistics firms like UPS & FedEx unfairly take advantage of the requirement by the USPS to deliver mail six days a week to over 160 million addresses at uniform, affordable rates. UPS/FedEx will receive the package and do the long haul. But then instead of driving the package to a final residential doorstep themselves (incurring high residential and fuel surcharges), they drop it off at a local USPS branch or regional hub. USPS letter carriers complete the final-mile delivery to the recipient's home or P.O. Box. It's literally part of their business model. UPS calls it 'UPS Ground Saver' and FedEx calls it 'FedEx Ground Economy'.

These hybrid services typically cost 20% to 40% less than standard UPS Ground or FedEx Ground. It takes longer to ship but UPS/FedEx bypass the steep residential delivery fees (often $6.45–$6.50+ per package) that private carriers charge for dropping off at houses rather than businesses. Also, it's the only way to deliver to PO Boxes because standard UPS and FedEx ground services don't do directly.

This is classic example of capitalism where private companies 'keep profits and socialize losses'. The 5% annual dividend paid by FedEx every year to shareholders is paid for by American tax-payers funding the last-mile delivery of packages at dirt cheap rates.
