The USPS is considered a “private corporation” but congress will not allow the USPS to compete like a private corporation. Every time the USPS tries to implement other revenue generating services, like other private corporations, congress gets yelled at by FedEx, UPS, et. al. and Congress makes the USPS shut down the competing services. If the USPS is a corporation then remove your congressional strangle hold from around the throat of the USPS and let them try to succeed and if FedEx et al don’t like it, tough!
Here’s a better idea.
Sell it off.
Privatize the USPS no strings attached.
The big difference is it is financed through user fees and not taxes.
The Republicans in 2006, who'd pledged to not raise taxes, got around their pledge by passing along a $5.3 billion bill to USPS to pay to help balance the budget. The thought was USPS could simply go out and raise postage to pay it off.
They forgot to tell the Postal Rate Commission that it was OK to charge off this $5.3 billion bill (For future ~ meaning "75 years in the future' ~ retiree's medical insurance), so they didn't.
USPS had been operating for several decades under a financial regime that kept it's expenses within 2% of revenues ~ to meet the legal requirement that it break even with no profit or loss.
$5.3 billion didn't exactly fit in anywhere so they borrowed the money to pay the bill.
As it is usps contracts with fedex and ups for long haul delivery of priority and express items.
