One problem with most current governments is that they prioritize economic growth (as mismeasured by GDP per capita) over citizens' happiness, quality of life, efficiency of trait display, and breadth and depth of social networks. The latter outcomes are not actually any harder to measure than GDP per capita. For example, the UN Human Development Index (HDI) measures overall quality of life fairly well by taking into account life expectancy, literacy, and educational attainment; this index puts Iceland, Norway, Australia, and Canada at the top, and the Democratic Republic of the Congo at the bottom.
