Money and Happiness

Measured a different way, the correlation between money and happiness is surprisingly strong (click here to go to the origin source)

DISMAL scientists who look at happiness often contend that, beyond a GDP per capita of just $15,000 (measured at purchasing-power parity), money does not buy happiness. Up to that point the correlation between the two is strong, but thereafter it falls away. If this is true then some heretical conclusions follow: rich America is no happier than poorer Brazil, so what is the point in people who live in rich countries working harder to get ever richer? Politicians should concentrate on maximising the mental health of their voters, rather than the size of their pay checks. But plot the data another way, on a logarithmic scale where each increment represents a 100% increase in income per head, and the relationship between wealth and happiness looks more robust.
