No one should be forced to wear a uniform under any circumstance. Uniforms are demeaning to the human spirit and totally unnecessary in a democratic society. Uniforms tell the world that the person who wears one has no value as an individual but only lives to function as a part of the whole. The individual in a uniform loses all self-worth. There are those who say that wearing a uniform gives a person a sense of identification with a larger, more important concept. What could be more important than the individual himself? If an organization is so weak that it must rely on cloth and buttons to inspire its members, that organization has no right to continue to exist. Others say wearing uniforms eliminates all envy and competition in the matter of dress, so that a poor person who cannot afford good-quality clothes will not be looked down upon by a wealthy person who wears expensive clothes. But these people ignore the important concept of freedom of choice, motivation and individuality. If all persons were to wear the same clothing, why would anyone strive to be better?
    It is like forcing everyone to drive the same car, have the same type of food. Uniforms also hurt the economy. If everyone was forced to wear uniforms, artistic personnel and sales personnel would be unnecessary. Why bother to sell the only items that are available? The wearing of uniforms would destroy the fashion industry. As a result, advertising would be unnecessary. Without advertising, newspapers, magazines, and television would not be able to remain in business. The entire information and entertainment industries would collapse.
