But the real relationship between income and happiness is more nuanced, and measuring people’s true feelings is tricky. For example, when study subjects are asked how happy they think people at different income levels are likely to be, they generally underestimate the happiness of the poor. And because much of the research considers just two variables, with income on one axis and happiness on the other, the other factors that can make us happy, such as personal relationships and health, are left out.
One of the best studies on the subject was done by economist Angus Deaton and psychologist Daniel Kahneman, winner of a Nobel Prize for Economics. The two, both professors at Princeton University, found that day-to-day happiness increases as income approaches $75,000 a year but then levels off. The reasoning is that having more money helps us cope with life’s problems, so we feel less sad and stressed. At the $75,000-a-year cutoff point, Deaton says, money is no longer as big an issue.
But Deaton and Kahneman distinguish between day-to-day happiness and life satisfaction. People at every income level who see a rise in income consider themselves more successful. So for every 10 percent rise in income, people gain the same amount of satisfaction, whether they’re making $50,000 or $500,000.
The two researchers conclude: “High incomes don’t bring you happiness, but they do bring you a life you think is better.” I think there’s a dimension that statement ignores. In his book “Rush: Why You Need and Love the Rat Race” (Hudson Street Press, $26), Todd Buchholz makes a convincing case that striving and achievement, which often correlate with higher salaries, enhance happiness. Buchholz, a former Harvard economics instructor and former White House adviser, says, “The truth is, most people have a deep need to work and to create.”
Note that Buchholz doesn’t say owning more stuff makes us happier. Cornell University psychology professor Thomas Gilovich says more stuff doesn’t make us happier for long. Gilovich, the author of one of my favorite books, “How We Know What Isn’t So” (Free Press, $19), says that possessions give us short-lived pleasure because we’re amazingly adaptable. When faced with a bad situation, adaptability can be helpful — we adjust to the situation and it no longer bothers us as much. But when it comes to material things, such as a big-screen TV, the pleasure we take in them drops quickly. People who seek more stuff end up on “a hedonistic treadmill,” he says.
It’s much better, Gilovich says, to spend money on doing things rather than buying things. Experiences, such as vacations and barbecues with friends, don’t seem to be as easily devalued by our adaptive abilities. “You get a lot more social value out of your experiences,” he says. “When you talk to people about your experiences, it tends to be an enjoyable conversation. You talk about material goods much less.”
And our experiences don’t lend themselves to easy comparisons, which gives them unique value. Gilovich points out that with a car, for example, comparisons are too easy: “Your car costs less money? It gets better mileage and it’s more reliable? Argh! You have a better car than I do!”
But, he says, “What if you went to Bali and I went to Hawaii? Well, Bali’s more exotic, but I went to Hawaii with friends and I have my memories, and I’m not worried by that comparison.”
