This report was commissioned by the United Nations Conference on Happiness and contains over a hundred pages of musings on world happiness. Its summary goes like this ” “GDP is important but not all that is important. This is especially true in developed countries, where most or all of the population has living standards far above basic material needs. Except in the very poorest countries happiness varies more with the quality of human relationships than with income. And in the richest countries it is essential not to subordinate the happiness of the people to the ‘interests of the economy,’ since the marginal utility of income is low when income is so high. The economy exists to serve the people, not vice versa. Incremental gains in income in a rich country may be much less beneficial to the population than steps to ensure the vibrancy of local communities or better mental health.” You can download it free from here . via fastcoexist
