I think how easy life is has little to do with psychological wellbeing. If life is very hard but you are doing great relative to others you will feel good. Furthermore, a more demanding life often generates a deeper sense of purpose and meaning.

It has to be something else. Lots of people around the world live in dire conditions, in sub-modern conditions, picking garbage dumps bathing in ditch water.

They're not doing "great" from an economic standpoint, but may be doing well from a social standpoint and mental health standpoint. They may not be individually tougher, but as a social group, they seem tougher.
