Have you noticed that in spite of great increases in wealth and improvements in technology in the last few decades, people don't seem to be any happier today than they used to be? Lane tackles this question head on, and finds some interesting answers. This book modestly blows most of today's conventional economics right out of the water.
Conventional economic wisdom is that increased GDP will solve all problems and make everyone's life better. Lane shows this isn't so. For the very poor, increased per capita GDP does indeed make people happier. Once the necessities of life are satisfied, higher GDP has little or no effect on how content people are with their lives. When you consider the lengths to which governments go to increase their GDP by a few percentage points, you begin to understand how important this finding is.
In the developed countries, Lane shows that people's overall satisfaction with their lives has been declining steadily in recent years. Lane finds that a decline in companionship and family life and an increase in television viewing are important factors in this. People are often not very good judges of what life choices will really make their lives better and happier. It is easy to fall into a trap of trying to get more money, while sacrificing the time it takes to maintain relationships with friends and family.
Some great quotes from the book:
". . . relieving poverty without creating dependency has proved difficult where it has been seriously tried."
"Consequently, it is possible to want to spend more than one earns--a sure prescription for misery, as Micawber once explained to David Copperfield."
". . . that magnificent apparatus of economic analysis might be turned to the purpose of improving well-being."
Lane does miss some things. I suspect that in the U.S. at least, part of the reason for the decline in happiness relates to the fact that people move around so much, which makes keeping up regular contact with relatives and friends difficult. The tendency for more people to attend college, and to go to colleges hundreds of miles away from their families, contributes to this rootless trend. I tend to think that Americans work more hours, and are encouraged to carry more debt, than is really good for society. I also suspect that the spread-out design of American cities, and the resulting huge time costs of commuting, play a role. For more on this, see Kunstler's book "The Geography of Nowhere."
As to the book itself, the writing is rather stodgy and academic. Lane hammers on the details of what studies show about life satisfaction and happiness, what the flaws of the various studies are, how the questions were asked, which results are the most robust. Lane is not trying to write an exciting book, he's trying to prove his points beyond doubt. I think he succeeds in that.
Lane sometimes seems to be asking more questions than he answers. There are enough possible topics for further research presented here to keep an army of graduate students busy. Unlike most economists and political scientists working today, though, I think Lane is asking the right questions. What kind of future do we really want? One in which everyone works 70-hour weeks, makes lots of money, and lives miserable and alone in a huge house? Or maybe we can come up with something better? Given the ecological pressures caused by the current lifestyles in the developed countries, rethinking this may be a matter of the survival of our civilization.
