This is hardly surprising, but it's nice to see it featured at CNN:
We are entirely capable of knowing what policies best contribute to people leading positive and rewarding lives.
In recent decades, social scientists have been studying human happiness in the same way we study any other human attribute. Vast new multidisciplinary research has emerged around the proposition that it is possible to empirically measure the extent to which people view their lives as satisfying.
So what conditions best promote more rewarding lives?
The answer is simple and unequivocal: Happier people live in countries with a generous social safety net, or, more generally, countries whose governments "tax and spend" at higher rates, reflecting the greater range of services and protections offered by the state. (These findings come from analysis of data from the World Values Surveys for the 21 Western industrial democracies from 1981 to 2007 for my book "The Political Economy of Human Happiness." Similar findings have been reported in peer-reviewed journals like "Social Research" and the "Social Indicators Research.")
The relationship could not be stronger or clearer: However much it may pain conservatives to hear it, the "nanny state," as they disparagingly call it, works. Across the Western world, the quality of human life increases as the size of the state increases. It turns out that having a "nanny" makes life better for people. This is borne out by the U.N. 2013 "World Happiness Report," which found Denmark, Norway, Switzerland, the Netherlands and Sweden the top five happiest nations.
