[R]esearchers analyzed the relationship between tax progressivity and personal well-being in 54 nations surveyed by the Gallup Organization in 2007—a total of 59,634 respondents. Well-being was expressed in people’s assessments of their overall life quality, from “worst” to “best possible life,” on a scale of 1 to 10; and in whether they enjoyed positive daily experiences (such as smiling, being treated with respect, and eating good food) or suffered negative ones, including sadness, worry, and shame. Finally, the analysis looked at the participants’ satisfaction with their nation’s public goods, from schools to clean air.
[...] On average, residents of the nations with the most progressive taxation evaluated their own lives as closer to “the best possible.” They also reported having more satisfying experiences and fewer discomfiting ones than respondents living in nations with less progressive taxes. [via TaxProf]
