Passage Four

Equal pay for equal work is a phrase used by the American women who feel that they are looked down upon by the society. They say it is not right for women to be paid less than men for the same work.

People who hold the opposite opinion(mainly men)have an answer to this. They say that men have more responsibility than women; a married man is expected to earn money to support his family and to make important decisions, and therefore it is right for men to be paid more. There are some people who hold even stronger opinion than this and are against married women working at all. When wives go out to work, they say, the home and children are given no attention to. If women are encouraged by equal pay to take full-time job, they will be unable to do the things they are supposed to. Women are best at making a comfortable home and bringing up children. They will have to give up their present position in society.

"This is exactly what they want to give up, "the women who disagree say. "They want to escape from the limited place which society expects them to fill, and to have freedom to choose between a job and home life, or a mixture of the two. Women have the right of equal pay and equal opportunities."

These women have expressed their opinions forcefully by using the famous saying, "All men are created equal." They point out that the meaning of this sentence is "all human beings are created equal."
