     In a family where die roles of men and women are not sharply separated and where many household tasks are shared to a greater or lesser extent, notions of male superiority are hard to maintain.The pattern of sharing in tasks and in decisions makes for equality, and this in turn leads to further sharing. In such a home, the growing boy and girl learn to accept that equality more easily than did their parents and to prepare more fully for participation in a world characterzed by cooperation rather than by the ” battle of the sexes” .If the process goes too far and man’s role is resided as less important - and that has happend in some cases - we are as badly as before,only in reverse.It is time to reassess the role of the man in the American family. We are getting a little tired of "momism”（妈妈当家），-but we don't want to exchange it for a ”neo-popism”（爸爸当家）.What we need，rather, is the recognition that bringing up children involves a partnership of equals. There are signs that psychiatrists,psychologists, social workers, and specialists on the family are becoming more aware of the part men and that they have decided that women should not receive all the credit - nor all the blame. We have almost given up saying that a woman's place is the home. We are banning, however, to analyze men ’s place in the home and to insist that he does have a place in it. Nor is that place irrelevant to the healthy development of the child.The family is a cooperative enterprise for which it is difficult to lay down rules, because each family needs to work out its own ways for solving its own problems.Excessive authoritarianism (独裁主义）has unhappy consequences, whether it wears skirts or trousers, and the ideal of equal rights and equal responsibilities is connected not only with a healthy democracy, but also with a healthy family.
