The America of 2007 is far richer than the America of 1977. Life expectancy is 78 years, up from 74 years. Our homes are bigger and crammed with more paraphernalia (microwave ovens, personal computers, flat-panel TVs). But happiness is stuck.
In 1977, 35.7 percent of Americans rated themselves "very happy," 53.2 percent "pretty happy" and 11 percent "not too happy," reports the National Opinion Research Center at the University of Chicago. In 2006, the figures are similar: 32.4 percent "very happy," 55.9 percent "pretty happy" and 11.7 percent "not too happy." Likewise, in most advanced countries, self-reported happiness has been flat for decades.
In international comparisons, the United States ranks lower in happiness than some smaller nations (Denmark, Ireland, Sweden) but much higher than many large countries with paternalistic welfare states (France, Germany, Italy). Governments can provide health care. But they cannot outlaw despair or mandate euphoria.

Iceland is the leader in a league table judging the European country best able to give citizens a long and happy life. Estonia comes bottom of the 30-nation survey while the UK lurks below Romania, at number 21 in the chart.
The European Happy Planet Index used carbon efficiency, life satisfaction and life expectancy to rate the countries. The survey, published by the New Economics Foundation and Friends of the Earth, reveals that Europe is now worse at creating well-being than it was 40 years ago.
