I don't understand the downvoting of this comment. What is being described is effectively tribalism.
Tribalism worked well for humans for roughly 350,000 years. Then we idiots come along and think that we've got a better way that is already showing its weaknesses and strain after just a couple of thousand years. Really? Maybe, just maybe our ancestors were on to something and there's something we can learn from them. No that couldn't possibly be it.
