Sadly you forget this is a game for a lot of people not a way of life.
game
1.
an amusement or pastime
3.
a competitive activity involving skill, chance, or endurance on the part of two or more persons who play according to a set of rules, usually for their own amusement.
Now skill is different level.
You don't require skill to be amused.
You can't demand people care or try there hardest when you play with people that have no interest in savage content.
Think of it like this.
k-12(dungeons) doesn't really teach you anything you need as an adult( beyond basic math and reading by grade 3) but it does teach you how to learn. And while there are some really dump people out there.
Collage and university(raiding) is where really skill comes in.
