Thank you.
A very good question. I think that if the White House had Teamster backing, the USPS might be toast. But, I don't see that backing coming any time soon.
Honestly, I really don't mind the government delivering the mail. What I object to is that the USPS has become a jobs program where white males must work 3 times as hard and have 3 times the education just to break even. Its a quota-factory. Your carrier is a front to make it appear that the main post offices in large cities really do work hard. They don't.
