In the most recent Presidential debate between Obama and Romney the equal pay issue was brought up again. As most of you probably know, there are people who believe that there is a systemic bias against women when it comes to wages. Not only does this not make much theoretical sense (why would companies hire men when they could get the same amount of work for 75% of the price?) but the data does not back it up either.
