Which means there is more demand for upper educated men since they are in demand by both educated and uneducated women. As another commented has suggested this might not be an issue when gender roles get removed, but I have a sneaking suspicion that this will just leave both parties unsatisfied with the result. I would argue that innate biological differences contribute to the different gender based desires, and hence affect the different gender roles.
