Take sex away from people. Make it forbidden, evil. Limit it to ritualistic breeding. Force it to back up into suppressed sadism. Then hand the people a scapegoat to hate. Let them kill a scapegoat occasionally for cathartic release. The mechanism is ages old. Tyrants used it centuries before the word "psychology" was ever invented. It works, too.
Robert A. HeinleinA woman is not property, and husbands who think otherwise are living in a dreamworld.
Robert A. HeinleinHappiness lies in being privileged to work hard for long hours in doing whatever you think is worth doing. One man may find happiness in supporting a wife and children. Another may find it in robbing banks. Still another may labor mightily for years in pursuing pure research with no discernible result. Note the individual and subjective nature of each case. No two are alike and there is no reason to expect them to be. Each man or woman must find for himself or herself that occupation in which hard work and long hours make him or her happy.
