There was a time when everyone thought that the Europeans and the Japanese were better at business than we were. In the early 1990s airport bookstores were full of volumes with samurai warriors on their covers, promising to teach you the secrets of Japanese business success. Lester Thurow’s 1992 book, “Head to Head: The Coming Economic Battle Among Japan, Europe and America,” which spent more than six months on the Times best-seller list, predicted that Europe would win.

Then it all changed, and American despondency turned into triumphalism. Partly this was because the Clinton boom contrasted so sharply with Europe’s slow growth and Japan’s decade-long slump. Above all, however, our new confidence reflected the rise of the Internet. Jacques Chirac complained that the Internet was an “Anglo-Saxon network,” and he had a point — France, like most of Europe except Scandinavia, lagged far behind the U.S. when it came to getting online.

What most Americans probably don’t know is that over the last few years the situation has totally reversed. As the Internet has evolved — in particular, as dial-up has given way to broadband connections using DSL, cable and other high-speed links — it’s the United States that has fallen behind.

The numbers are startling. As recently as 2001, the percentage of the population with high-speed access in Japan and Germany was only half that in the United States. In France it was less than a quarter. By the end of 2006, however, all three countries had more broadband subscribers per 100 people than we did.
