There is truth in your post. Our hunting culture ethics and mores (not to mention supportive technology) have changed for the better in the last 100-125 years. Traveling cross country by horse or wagon without refrigeration, it would be hard to eat even a whole deer before it spoiled- at least without jerking it, which takes time they often could not afford - so it was 2 or 3 days worth of take along, and kill another. Those two week pack trips with only camp meat salvaged were part of the transition, thankfully gone now.
"and find that an predator had gotten the meat that night.....and they didn't worry about it in the least. Instead, they just went out and shoot another one."
Still happens in my part of the country, as does a bunch of other stuff "Cultural", and often non-cultural related. Enforcement is spread so thin over so much area... and there is so danged much country that many incidents never get discovered.
Troopers claim they nail miscreants in 80% of their cases. I would add that that's just the ones they become aware of. Of course, it helps when someone drops a form of ID at the site, or backs their license plate into an impressionable snowbank, all of which has happened.
I once had a caribou kill hit overnight by a brown bear, but it didn't do much damage, preferring the gut pile which had rolled 50 yards or so down the steep slope. It ate the liver, bit the heart, cleaned off the brisket is all. And dropped about 5 gallons of blueberry poop all around, but not fouling the carcass. One of the kids hit one little "tangy" piece of meat and accused me of not "cleaning off all the bear slobber".
. Bear was still on the gut pile the next morning, and was a bit disgruntled at my language, all the way out of sight. Most likely came back later.
You can read one such example of "cultural" norm (often referred as "white man's rules") posted today on the Alaska forum. Best part on that one is these guys were probably Narked out by someone they bragged to. Slobs in every culture, of course.
I watch "Wardens".
