According to Marx and Engels the women in family was treated just as a capital like any other means of production. Women produced children which were very valuable assets. Thus women, according to Marx and Engels, were reduced to the status of producer of children, domestic servant, and means of satisfying lust.
Furhter, Marks and Engels contended that family became a means of protecting the class structure by passing on property from father to son. They said that in prehistoric days the society was jointly responsible for bringing up children, and that the institution of family was invented with the specific purpose of establishing ownership rights over women and the children.
