The Organization for Economic Cooperation and Development says people in Denmark, Finland and the Netherlands are the most content with their lives. The three ranked first, second and third, respectively, in the OECD's rankings of "life satisfaction," or happiness.
There are myriad reasons, of course, for happiness: health, welfare, prosperity, leisure time, strong family, social connections and so on. But there is another common denominator among this group of happy people: taxes.
Northern Europeans pay some of the highest taxes in the world. Danes pay about two-thirds of their income in taxes.
