planting a field of soybeans, designing a radio that will work in the shower—leads to a thriving and ever-improving standard of living for most (though not all) members of society.
    Economists sometimes ask, “Who feeds Paris?”—a rhetorical way of drawing attention to the mind-numbing array of things happening every moment of every day to make a modern economy work. Somehow the right amount of fresh tuna makes its way from a fishing fleet in the South Pacific to a restaurant on the Rue de Rivoli. A neighborhood fruit vendor has exactly what his customers want every morning—from coffee to fresh papayas—even though those products may come from ten or fifteen different countries. In short, a complex economy involves billions of transactions every day, the vast majority of which happen without any direct government involvement. And it is not just that things get done; our lives grow steadily better in the process. It is remarkable enough that we can now shop for a television twenty-four hours a day from the comfort of our own homes; it is equally amazing that in 1971 a twenty-five-inch color television set cost an average worker 174 hours of wages. Today, a twenty-five-inch color television set—one that is more dependable, gets more channels, and has better reception—costs the average worker about twenty-three hours of pay.
    If you think that a better, cheaper television set is not the best measure of social progress (a reasonable point, I concede), then perhaps you will be moved by the fact that, during the twentieth century, American life expectancy climbed from forty-seven years to seventy-seven, infant mortality plunged by 93 percent, and we wiped out or gained control over diseases such as polio, tuberculosis, typhoid, and whooping cough. 2
    Our market economy deserves a lot of the credit for that progress. There is an old Cold War story about a Soviet official who visits an American pharmacy. The brightly lit aisles are lined with thousands of remedies for every problem from bad breath to toe fungus. “Very impressive,” he says. “But how can you make sure that every store stocks all of these items?” The anecdote is interesting because it betrays a total lack of understanding of how a market economy works. In America, there is no central authority that tells stores what items to stock, as there was in the Soviet Union. Stores sell the products that people want to buy, and, in turn, companies produce items that stores want to stock. The Soviet economy failed in large part because government bureaucrats directed everything, from the number of bars of soap produced by a factory in Irktusk to the number of university students studying electrical engineering in Moscow. In the end, the task proved overwhelming.
    Of course, those of us accustomed to market economies have an equally poor understanding of communist central planning. I was once part of an Illinois delegation visiting Cuba. Because the visit was licensed by the U.S. government, each member of the delegation was allowed to bring back $100 worth of Cuban merchandise, including cigars. Having been raised in the era of discount stores, we all set out looking for the best price on Cohibas so that we could get the most bang for our $100 allowance. After several fruitless hours, we discovered the whole point of communism: The price of cigars was the same everywhere. There is no competition between stores because there is no profit as we know it. Every store sells cigars—and everything else for that matter—at whatever price Fidel Castro (or his brother Raul) tells them to. And every shopkeeper selling cigars is paid the government wage for selling cigars, which is unrelated to how many cigars he or she sells.
    Gary Becker, a University of Chicago economist who won the Nobel Prize in 1992, has noted (borrowing from George Bernard Shaw) that “economy is the art of making the most of life.” Economics is the study of how we do that. There is a finite
