Both genders have equal representation in the noble or sleazy categories instead of the usually-now-dominant females being like the worst examples of males are now, and the males being mostly submissive - should be a mix, as there is in reality (you only hear about the extremes, so they seem to dominate, but in a true reversal, the media would be more interested in the ones who aren't sleazebags so perception would be the opposite).
