yeah... interesting to see what happens in more atheistic countries (EU). Eastern countries (eg Japan?) dont always have a god. but do have collectivist/in group leanings.
Idiot "economists" who try to use Japan as an example of how to do things IGNORE the fact that it's a mono-ethnic state with it's border completely surrounded by a big beautiful wall.
if your hypothesis about religion is true, then cultures with less religion should be less cohesive/trusting/successful. idk if Japan is a good example, just what came to mind.
