The bulk mail section of the us mail, is nothing more than an affirmative action hiring center, sell it to several trucking firms and stop the bleeding and deliver mail three days a week, and no more buying employee houses.
The house buying trick is not unknown in the private sector. In fact, with some industries it's so normal they don't imagine it could be any other way.
The problem with USPS is it's not private industry and has a bunch of people sniffing it's nether regions constantly ~ they are called "the public" and they think they own the place.
As far as EIEIO hiring the USP is America's largest single employer of African-Americans. Yet, they have to meet the same high standards as the white people. No stealing. No dawdling. No using dope. Etc. All pretty basic stuff. It's been that way since LONG BEFORE EIEIO.
