     Among rich countries, people in the United States work the longest hours. They work much longer than

in Europe. This difference is quite surprising because productivity per hour worked is the same in the United

States as it is in France, Spain and Germany, and it is growing at a similar speed.

     In most countries and at most times in history, as people have become richer they have chosen to work

less. In other words they have decided to "spend" a part of their extra income on a fuller personal life. Over

the last fifty years Europeans have continued this pattern, and hours of work have fallen sharply. But not in

the United States. We do not fully know why this is. One reason may be more satisfying work, or less

satisfying personal lives.

     Longer hours do of course increase the GDP (国内生产总值). So the United States has produced more

per worker than, say, France. The United States also has more of its people at work, while in France many

more mothers and older workers have decided to stay at home. The overall result is that American GDP per

head is 40% higher than in France, even though productivity per hour worked is the same.

     It is not clear which of the two situations is better. As we have seen, work has to be compared with other

values like family life, which often get lost in interest. It is too early to explain the different trends (趋势) in

happiness over time in different countries. But it is a disappointing idea that in the United States happiness has

made no progress since 1975, while it has risen in Europe. Could this have anything to do with trends in the

work-life balance (平衡)?
