This is something I've been wondering for a while, because logically from a company's point of view, you always do what maximizes your profit ie: raw numbers that can't be skewed by prejudice. Assuming that companies are for the most part logical, why would they hire any men at all if women are doing work of similar quality and they could reduce their total costs by only paying their workers the smaller "women's wage"? Since this is not the case, gender based pay inequality logically doesn't exist. I know the myth of a gender based income gap has been debunked many times, but is this not at least a useful and compelling argument?
