> "Life shouldn't be a zero sum game" is an anti-competitive meme

Disclaimer: I'm defining "anti-competitive meme" as some idea that is vulnerable to The Prisoner's Dilemma (aka. tragedy of the commons, or "why we can't have nice things").

It is! No different than "peace" is an anti-competitive meme, or "turn the other cheek" or "do not follow eye-for-an-eye" are all anti-competitive memes.

Arguably the goal of religion is to use the supernatural to keep anti-competitive memes prioritized within society.
