Gender Inequality

It is sad to still see gender inequalities in todays' society. A woman nowadays not only can run the home, but also works full time, runs errands; and still, men are seen as the patriarchs? I find that hard to believe. In the societies that have a mother and father (like my own household), everything is split in two equal parts, and we are both seen as the "patriarch" of the family, not one over the other. But still, women in 2012 are still being paid less money than their male counterparts in many fields of work. It is getting better than the 1970's to now; between 1970 and 2009, the ratio of men to women's earnings for full time, year round work has increased from 62 to 82.1%. Why, I do not understand, is it not 100% across the board? Women do just as much work in these fields as their male counterparts, and are getting treated unfairly when it comes to pay. I can only hope that 10-20 years from now, it will be equal.
