How do people spend extra money?

Here are the facts of the day:

Real per capita GDP in the United States is now three times higher than it was in 1958. What have people been spending all that extra money on? Is it all dictated by advertisers and salesmen who are inventing needs?

According to my calculations comparing 1958 and 2005 data from the U.S. Department of Commerce, Americans spent 27 percent of the huge increase in income between 1958 and 2005 on medical care, 23 percent on their homes, 12 percent on transportation, 10 percent on recreation, and 9 percent on personal business activities.

The kinds of things that advertisers and salesmen typically promote were relatively unimportant. Food got only 8 percent of the extra money, clothing only 3 percent, and personal care 1 percent.

Unfortunately, idealistic activities also received little of the extra money: 3 percent for welfare and religious activities, and a similar share for education. Thus most of the extra money was spent on health, a nice home, travel and relaxation, and doing a little business.

This might provide some clues on the consumption trends of China in the next a few decades.
