Who backs the retirement funds if the company folds and loses the retirement funds?The Post Office is an example of what government employee unions can do to a business. UPS and FEDEX employees make as much as postal service employees and they aren't losing billions of dollars a year. And, they are not allowed by law to process first class mail, even though they do transport a helluva lot of mail and packages on contract for the USPS.
You left something out. What other business is forced to prepay 5.5 billion dollars EVERY year to pre-pay well in advance for retirement benefits? How much do you think lobbyists for UPS and FED EX paid for that little gem of legislation? And you KNOW that those two companies would not deliver mail anywhere they deemed "unprofitable". You want to know what I don't understand, when did you morons on the right decide that EVERYTHING must have a profit motive behind it? Some things work better in a non-profit scenario, and they are ALWAYS cheaper and more efficient.
All corporations are required to fund their retirement programs dumbass. The Post Office has a monopoly on first class mail and is supposed to make a profit to in order to stay in business.
