“But Stevenson and Wolfers scoured the literature for what longitudinal studies there were, and found that in eight out of nine European countries, happiness increased between 1973 and 2009 in tandem with the country’s rise in GDP per capita.24 A confirmation for the world as a whole comes from the World Values Survey, which found that in forty-five out of fifty-two countries, happiness increased between 1981 and 2007.25 The trends over time close the books on the Easterlin paradox: we now know that richer people within a country are happier, that richer countries are happier, and that people get happier as their countries get richer (which means that people get happier over time).” (Steven Pinker, Enlightenment Now)
