Why even posit that to begin with, when we have plenty of science - psychology, sociology, behavioral economics, etc - that are intensely interested in human behavior? We have actual data and reasonably useful models to draw on. What you describe is the setting for a Young Adult fantasy series. Which is fine, and interesting for a while, but not a good way to think about how we would like our society to function. Go read Hannah Arendt's "On Violence", if you haven't. Or "Eichmann in Jerusalem." It's the banality of evil that's the really unsettling thing.
