Happiness peaks or levels off beyond $75k income? Wrong!

This often bandied about claim (http://content.time.com/time/magazine/article/0,9171,2019628,00.html), that happiness maxes out at $75k/year is due to a shallow and wrong reading of the research (https://www.pnas.org/content/107/38/16489.full).

Actually, life satisfaction keeps improving with income, with no limit.

Even emotional wellbeing doesn't always peak at $75k - it depends on local cost of living (https://medium.com/financial-strategy/the-dirty-little-secret-about-money-168edd36a2ee).
