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.
Basically you need to have a reason to TRUST your neighbor for capitalism to work. In Japan that reason is ethnic. In America it's JESUS.
I do not think people are honest because they are christian. They’re honest because they have a reputation irl or online. Ebay ex, sellers must to have reputations near 100%.
