As a result, the HDI represents a kind of happiness for each country. While the U.S. has an index of 91.5 and ranks about 8th, Norway leads all with 94.4 even as Sweden lags with 90.7. The HDI shows the overwhelming success of capital free markets in buying HDI points and the indisputable failure of social big government to even acquire a reasonable HDI.
However, HDI happiness is not cheap and the graph below shows the how much 100 HDI points cost in terms of tax as %GDP. The U.S. pays about one third as much as Norway for the same happiness, 11.5 versus 28.9 taxes%GDP per 100 HDI's. The U.S. pays a much lower %GDP for its HDI than many less efficient countries that overpay for their happiness. The U.S. along with Switzerland, Germany, Canada, and Japan pay for happiness with much more efficient economies than Norway, France, or UK.
China and Russia, for example, are at 72.7 and 79.8, respectively, and while China pays 14.6 taxes%GDP per 100 HDI, Russia pays 18.9 taxes%GDP per 100 HDI of happiness. The higher costs of happiness are very apparent as the inefficiencies of socialist big-government versus capitalist free market economies.
A desirable life is much more than just living longer and must include the pleasure of discovery as well as the compassion for others. It is clear that knowledge about the world and the skills to contribute to civilization both allow us to truly discover the future that each of us desires.
