WASHINGTON -- They say money can't buy happiness. They're wrong.
At least up to a point.
People's emotional well-being -- happiness -- increases along with their income up to about $75,000, researchers report in Tuesday's edition of Proceedings of the National Academy of Sciences.
For folks making less than that, said Angus Deaton, an economist at the Center for Health and Wellbeing at Princeton University, "Stuff is so in your face it's hard to be happy. It interferes with your enjoyment."
Deaton and Daniel Kahneman reviewed surveys of 450,000 Americans conducted in 2008 and 2009 for the Gallup-Healthways Well-Being Index that included questions on people's day-to-day happiness and overall life satisfaction.
Happiness got better as income rose but the effect leveled out at $75,000, Deaton said. On the other hand, their overall sense of success or well-being continued to rise as their earnings grew beyond that point.
"Giving people more income beyond 75K is not going to do much for their daily mood ... but it is going to make them feel they have a better life," Deaton said.
Comparing their life-satisfaction results with those of other countries, the researchers said the United States ranked ninth after the Scandinavian countries, Canada, the Netherlands, Switzerland and New Zealand.
