It’s like some people completely ignore the fact that a civilization cannot survive without people giving a shit about other people who aren’t related to them. The higher the proportion of stupid, selfish assholes there are in your civilization, the faster it will collapse. Cooperation with non-relatives is the only reason why we managed to evolve from the savanna and not get completely wiped out by other animals who are bigger and stronger than us. Behavioralists have classically called it altruism but, in reality, it’s enlightened self-interest.
