I spent much of my youth in Utah, and it is probably the epitome of this.
Best state Gini coefficient [0]. Great income mobility (also best in US [1]).
It also has a rampant fraud/ponzi/mlm issue [3]. They come from the same source- There is a general level of trust that is much higher than anywhere else I've lived or experienced. Mostly rooted in a trust in others is part and parcel of the culture and dominant religion. I don't think the upsides would be achievable without the downsides that seem endemic to it.
I’ve lived in Tokyo for 14 years and think that this characterisation also applies here. Comparatively low Gini coefficient, very high level of community trust and susceptibility to endemic fraud.
