And that led it to be adopted by a much larger tribe—the business tribe. You cannot wear a tie if you work with machinery. So wearing a tie became a sign that you were a man who used your brain to make a living, rather than your hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who didn’t wear a piece of colored silk around his neck. This is how millions of people came to be wearing ties across the world. They are part of the uniform of business. “Ties offer a point of indifference,”says John Milne, head of the British Guide of Tie Makers.“They give a chance to say something about their own personality.” So if you happen to meet a man with a very brightly colored tie, there is a good chance that he is the office joker. There is also a good chance that he will be wearing brightly colored socks. Is there a future for ties? The signs are not promising. Tie wearing seems to rare amongst the new bread of entrepreneurs(创业者) in the Internet and new technology industries. Many political leaders, including British Prime Minister Tony Blair, now go without ties. This shows they are men of the people—but not the people wearing ties. Up until around 1960,it was common for men across the Western world to wear hats as part of their business uniform. That changed with the election of John F.Kennedy to the presidency of the United States. Kennedy never wore a hat—in fact his nickname was“hatless Jack”.Seeing that the most powerful man in the world did not have to wear a hat, millions of other men decided that they did not have to,either. Hats simply vanished across the Western world. Perhaps“tieless Tony”(UK Prime Minister Tony Blair) will have the same effect as“hatless Jack”. 1.
