Quote by Frederick Engels

“In some ways it is the ultimate alienation in our society that the ability to give birth has been transformed into a liability. The reason is not simply that, since women bear children, they are more limited in their movements and activities. As the foregoing discussion indicates, this was not a handicap even under the limited technology of hunting-gathering life; it certainly has no relevance today. ... The subjugation of the female sex was based on the transformation of their socially necessary labor into a private service through the separation of the family from the clan. ... The separation of the family from the clan and the institution of monogamous marriage were the social expressions of developing private property; so-called monogamy afforded the means through which property could be individually inherited.”
