I strongly contend that there very likely has not been a decline in the give-a-damn factor. My experience is that it really hasn't ever been too high. Just look at cartoons 50 years ago, and packages getting wrecked en route is a staple joke; the jokes were rarely obscure, but often topical. There is always a few great operators, but mostly you just fix you processes so people default to failure less. Hence hacks like the TV stamp.

But the answer is (as always) more automation. Mind, this can lead to really neat edge cases where you accidentally build a package smashing factory. But in general repeatability (machine) beats out diligence (people) every time.

You just have to, you know, pay for it. The cost benefit analysis probably strongly favors the marked box in this case.
