I spent last week at the Aspen Ideas Festival, talking about Betsey’s and my research on the Economics of Happiness. You might think that my message—that income and happiness are tightly linked—would be an easy sell in Aspen, which is the most beautiful and most expensive city I’ve ever visited. But in fact, it’s the millionaires, billionaires and public intellectuals who are often most resistant to data upsetting their beliefs. You see, the (false) belief that economic development won’t increase happiness is comfortingly counter-intuitive to the intelligentsia. And it’s oddly reassuring to the rich, who can fly their private jets into a ski resort feeling (falsely) relieved of any concern that the dollars involved could be better spent elsewhere.
