Why don't many women have their hair up to their butt?

This has got to be one of the less rocked female hairstyles and I've noticed barely any women have it, something many women have told me (nothing to do with this topic) is that long hair is just hard to maintain and thats what im assuming is the reason so is this the only reason or are there others that women don't go past the shoulders?
