Organized crime and USPS

Let's compare:

• You have to use them
• If you mail something and want it to get there, you have to buy protection for it, otherwise, it may or not get there and if it doesn't there is nothing you can do about it
• They don't actually have to do what you paid them to do and correctly deliver mail
• If you have protection, there's still a good chance you can't do anything about it, because the tracking you buy doesn't always/often track that they have it, so they can deny that they lost it.
• If you have protection and they misdeliver it, you still can't do anything, because you have nothing to show that they broke or damaged or lost it- you only have their word that it's delivered and nothing to show for it. They say they delivered it, you say they didn't... what are you going to do- yell 'liar liar pants on fire?'
