That's purely subjective, although as for the classics, this is because of tradition and rules in which men were to go to school then work while women were to stay at home with the children. If it was discovered that a woman was doing "man's work" or anything other than household chores, then she was reprimanded. This is why as time goes on, more women join the work force as well as write books.
Well, you can buy into the idea that we as a culture put the cabash on women whenever they try to do something, or you can figure that women in general aren't driven to become accomplished in any particular field as men are. Your choice. PC says we do it to them on purpose. Personally, I say, if you wanna do something, just do it and quit whining about it.
