There are many aspects of the women’s liberation movement. Some women agree with all of the goals of women’s liberation. They want full equality with men in every aspect of life. In marriage, they want husbands and wives to share all of the work and responsibilities of a home and family. In work, they want women and men to have the same jobs and the same chance to succeed. They want women to be paid just as much as men are for the same work. Other women agree with some of the ideas of women’s liberation. They want the same pay if they hold the same jobs as men. At home, however, they do not expect their husbands to share in the cleaning, cooking, and other household jobs.
It is important to remember that the women’s liberation movement is not concerned only with concrete issues. The movement is also concerned with attitudes and beliefs. One example of this concern is the issue of a woman’s identity. A woman’s identity is what she thinks of herself as a person, who she thinks she is, and what she thinks she can do. Some women do not think they are capable of doing anything important. The women’s liberation movement has helped these women improve their view of themselves. Many women who are concerned with women’s liberation have taken jobs, have helped others, have raised healthy children, and have done many other things to contribute to their communities. They have shown that they are capable of being good leaders and of doing many important things.
The "concrete issues" are those which ______.
