I think the question involves breeding over the centuries. Woman were 2nd class for centuries, and thus not given the same education, but currently in quite a few socities they are given equal educations. I know where I am, quite a few of the girls in my kids classes are equals in math, or beyond. Just like many areas of life over the centuries, breeding purposes make a difference, and is a valid reference point to look at and reference to development. We all may have a valid equality when we are born, but ****heads with a bias can change out development, and thus the development of future generations. All should have an equal chance for education.
