When the holiday rush comes around, does UPS pay to train new employees or do they just throw up their hands and say that it will now take a month to deliver a package? And how does UPS avoid its customers being not "willing to pay higher bills" for the sake of training new employees? And what stops Fedex from being a free rider that poaches the new UPS employees right after they're trained? Your whole argument is just beating down criticism by taking the current broken incentives as if they're set in stone. Yes, we know the incentives of the current system are terrible. In fact that's exactly why the whole system needs to be overhauled with sweeping reforms, rather than waiting for it to get better on its own.
