After the war the women of the German Democratic Republic were drawn into helping rebuild their nation with the promises of equal pay for equal work and good day-care centers for their children. As a result of the government's campaign over 80 percent of eligible (有条件的 ) women hold jobs. One-third of East Germany's doctors and judges, 11 percent of its mayors and one-third of its college graduates are women.
But there are clouds in the heaven of liberation. The liberated woman is more than a little enthusiastic about the way she is liberating herself from her husband. East Germans have the eighth-highest divorce rate in the world. The reason for divorce is probably more often the competition between husband and wife than it is adultery (私通). The dominant role of man in marriage will end when his economic superiority ends. Men are more willing to joke about helping their wives than to help them in the kitchen. They still cling to the idea that housework and bringing up children are women's work. As one young East German housewife puts it, "equality means my husband and I have equal rights. Equal rights means that we both work at full-time jobs. Then I clean the house and take care of the children while he sits in front of the television set and drinks beer in the evening."
