Three more observations about what we can learn from this history:
1) The income-well-being relationship has appeared just about as strongly in surveys probing happiness as in surveys asking about life satisfaction. (There are exceptions.)
2) One interpretation of the 2006 Gallup data is that it is still all about relative income comparisons: In today’s global village, folks in Jamaica may be comparing their lot in life to the greater prosperity they observe when watching U.S. television shows. Countering this, it looks, to my eye, as though the income-happiness link appears about as strong in countries that are truly plugged in to the global village, as those that are less engaged.
3) Moreover, the relationship between income and happiness is about as strong today as it was in the very first surveys, which were taken sixty years ago, when the world was less integrated.
