Very true. Triangle of Sadness was a good movie kind of about this.

When the shit hits the fan the guy in charge of the bunker is going to be the one who knows how to clean off the fan and get the air filtration system running again.

.. or the guy willing to violence. shorter movie but equally probable.

Violence can only get you so far. Sure, maybe the guy who knows how to get food will get you some food if you threaten to kill him. But if he refuses, and you do kill him, then what? You still don't know how to get food for yourself.

people in the violence frame aren't doing the long term thing. but we absolutely know they exist and in no scenario can you be assured they're not in that position.

it's gambling, pure and simple.

Yeah, people are smart though. Like if you’re good at getting food you find the person who’s best at violence and promise to get them plenty of food if they protect you from the other violent people. Maybe you divide up the work among the good at food getting people and the good at violence people and pretty soon you got yourself a little society going.

people capable of violence don't need to be smart, because they're capable of violence.

the point is, you cant rely on a scenario where society breaks down, that survivors will act more rational then than they do now.
