Do "beauty" contests (Mr. America, Miss America, etc.) serve any purpose in society?

No, I do not think that "beauty" contests are a purpose in society. Who are we to judge the looks and brains of someone whether or not they should represent us as the most salient person of our state. Whats the point in that? It is very pointless, what do they earn besides publicity of the most gorgeous person. I am just disagreeing, this just does not make much since to me but give them something to do in life.
