The USPS is managed by morons, who should be placed in a facility. It operates at a loss, because the management does not know what to do, other than play with their thumbs. Management wants the USPS to be privatized, so they are doing everything in their power to destroy the USPS.
The USPS gives money to Amazon for no apparent reason, charging half what UPS and FedEx charge to deliver packages. Meanwhile, they pay the drivers $15 an hour, with no benefits at all, and no full-time hours. They use part-time, disposable temp workers. Very few drivers are full-time, with benefits. The USPS does not provide good jobs to most of its employees. Instead, it is far worse than Wal-Mart. The driver jobs are noisy, dusty, long hours for little pay, and the vehicles are unheated, uncooled, violent, and liable to cause severe, permanent hearing loss in drivers. For $15 an hour, a driver can expect to lose 25% of his hearing for life, suffer injury to joints, bones and tissue, and possibly lose a limb, because the little jalopies the drivers run around in on dirt roads for twelve hours at a time are unsafe, antiquated WW2-style jeeps.
