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.
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.
it's gambling, pure and simple.
