Women have always had lower status than men, but the extent of the gap between the sexes varies across cultures and time (some arguing that it is inversely related to social evolution). In 1980, the United Nations summed up the burden of this inequality: Women, who comprise half the world's population, do two thirds of the world's work, earn one tenth of the world's income and own one hundredth of the world's property. In Leviticus, God told Moses that a man is worth 50 sheikels and a woman worth 30--approximately the contemporary salary differentials of the sexes in the United States.  (Actually, according to one "Current Population Survey" of the US Census Bureau, American women in 1999 earned approximately 77% of what men made, in 2000, according to the Department of Labor, their median weekly earnings were 76% of the male median.)  What might be the socio-cultural implications if men were to also be the child bearers?
