The Myth of the Wage GapThis is a short piece marketplace did on the gender "wage gap." The whole piece revolved around the opinion that while employers aren't consciously paying women less, there exists what Heidi Hartman calls "institutionalized societal differentiation" that burdens women with an unfair share of the childrearing burden and holds them back economically.
Hello..... anyone heard of the word CHOICE? Women don't have to have children. It's a choice that they make that affects their earning potential. That is why women earn $0.76 for every dollar a man makes- because they are CHOOSING to become teachers rather than engineers, and nurses rather than lawyers. If having children is of high enough value to you, you will sacrifice higher wages for the joy of having a family.
Society does not owe workers more money based on their family status. This would be paying people based on "need" instead of merit. Last time I checked the philosophy "from each according to his ability, to each according to his need" doesn't work very well.
