Due to the popularity of the question (especially on BHW), Columbia University decided formulate a definite answer. The list of the happiest countries in the world: Denmark, Norway, Switzerland, the Netherlands and Sweden are the world's happiest countries, according to the survey of 156 countries. Rwanda, Burundi, the Central African Republic, Benin and Togo -- all nations in Sub-Saharan Africa -- are the least satisfied with their lives, the report said. The United States came in at number 17 in the world in terms of overall happiness, but it still lags behind Canada (6), Australia (10), Israel (11) the United Arab Emirates (14) and Mexico (16), according to the Earth Institute. The report ranks the United Kingdom as the 22nd happiest country in the world. Other major nations included Germany (26), Japan (43), Russia (68) and China (93). Original story: http://edition.cnn.com/2013/09/09/business/earth-institute-world-happiness-rankings/?hpt=hp_c3 The funny thing - the 10 happiest countries in the world pay the most taxes (between 30% and 40%). So my old theory still holds, better find a new planet.
