     Americans are proud of their variety and individuality, yet they love and respect few things more than

a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general . Why are

uniforms so popular in the United States?

     Among the arguments for uniforms, one of the first is that in the eyes of most people they look more

professional than civilian(百姓的)clothes . People have become conditioned to expect superior quality

from a man who wears a uniform . The television repairman who wears uniform tends to inspire more

trust than one who appears in civilian clothes . Faith in the skill of a garage mechanic is increased by a

uniform . What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional

identity(身份)than to step out of uniform?

     Uniforms also have many practical benefits . They save on other clothes . They save on laundry bills .

They are tax-deductible(可减税的) . They are often more comfortable and more durable than civilian

clothes.

     Primary among the arguments against uniforms is their lack of variety and the consequent loss of

individuality experienced by people who must wear them . Though there are many types of uniforms, the

wearer of any particular type is generally stuck with it, without change, until retirement . When people

look alike, they tend to think, speak, and act similarly, on the job at least.

     Uniforms also give rise to some practical problems . Though they are long-lasting, often their initial

expense is greater than the cost of civilian clothes . Some uniforms are also expensive to maintain,

requiring professional dry cleaning rather than the home laundering possible with many types of civilian

clothes.
