Switzerland is one of the richest countries in the world, and its citizens are pretty wealthy as well, as evidenced by its average wage of $35,952. With 80 percent of the people holding a paid job and 88 percent having completed secondary education, there is no doubt that Switzerland has earned its rank. An incredible 97 percent of the people are happy with the quality of water in the country. A small blip on these fantastic achievements is that Switzerland’s pollution rate is still high when compared with the OECD average.
