“All men are created equal” is one idea that nearly every American would agree upon.  36 they sometimes betray the idea in their daily lives, they have a deep faith  37 in some fundamental way no one is born superior to anyone else.
In the early years of American history, because titles of nobility(贵族) were forbidden, no  38 class system developed in the United States. Firmly believing that being born into a lower class would not  39 them from success and they would have a better chance in America, thousands of immigrants   40 to leave the European societies, where their    41  in life was determined  42 by the social class into which they were born. It was because the dreams of many of there immigrants were   43 in their new country, though there might be  44 in some situations, that Americans came to believe in equality of opportunity.
Americans do not mean that everyone should be  45 equal when they say they believe in equality of opportunity.  46 , they do mean that each person should have an equal chance for success.

However, competition is the price to be   50  for his equality of opportunity. Americans match their energy and intelligence against that of others in a competitive contest for success, because they believe competition  51 the best in any person. Indeed, the pressure of competition causes an American to be   52 , but it also places a constant emotional stress on him. In fact, in a society that gives so much  53  to those “winners”,   54 does not compete successfully for whatever reason never  55 into it as well as those who do.
