I have no problem with the Post Office except when people that work there say that their benefits and salary are not due to the government. They do perform a service, it is just a shame that they can’t do it at a profit.
I blame much of that on the unions. Without them, they just might make a viable enterprise (as it really should be). The unions demand way too much in both pay and restrictions to the working environment. That has to change in the future or the Post Office can and should go extinct.
As to the current environment, haven’t used the post office in years thanks to UPS and FedEX and the Internet. If it were my choice, I would eliminate them entirely and same many billions.
Remember, the United States alone has half the mail in the world. That's because we have the world's most efficient and least costly mail system.
It doesn't get better than that even where private companies move the mail.
