It is a combination of laziness, incompetence, and flat-out MALICE. I should NOT have to pack something to survive an airplane crash to mail it! I should NOT have packages left out in the rain THREE FEET AWAY FROM A COVERED PORCH! I had an oil sample container returned to me that looked like someone had run over it with a forklift! (I suspect that was because someone DID, in fact, run over it with a forklift.)
