The OECD (Organisation for Economic Co-operation and Development) measured a variety of countries against dozens of criteria relating to health, economics, community, environment, etc. Not surprisingly, the US is not the top country in every category. No country is. The US is high for income and the number of people properly housed, but very low on work-life balance. Overall, Americans give America a general satisfaction of life score of 7.2, above the world average of 6.6. If you want to know how America ranks, rather than just saying “We’re #1!” it is possible to actually dive into the data and find out “We’re #12!” at least as for life satisfaction.
