Agreed. There is so many factors to take into consideration when comparing compensation between men and women. For instance, there is no mention in the article of commute time to work. Men typically commute farther to work than women do.  The reason for this is simple. Men will travel farther for higher wage jobs. Men also typically work in more dangerous occupations. When one begins to to account for all the variation in work related choices my suspicion is that the wage gap between men and women will disappear.
