Happiness isn't a useful metric by itself. Happiness needs to be stable, stability requires power, and power requires relative wealth. In the long run inequality undermines happiness, even if you've met some happy poor people. Look at the native American population. They were happy until the weren't: when a culture with greater financial power wanted what they had and they didn't have the power to stop it. Or look at Somali pirates: happy fisherman. Until foreign powers dump waste in their fishing waters for decades, then they lose their economy and have to arm themselves to defend their waters. No more happy. Because they couldn't fund a proper navy. The point being -- know the difference between weather and climate.
