It's only fair. We have ghouls, but they can be human or animal. Doesn't really help even out the sexism.
Oh, right. Not everyone has — To make a VERY long story short: religious fanatics decided mages couldn't roam around freely because we're dangerous or something, so they started rounding up anyone who showed magical ability and kept them in towers. You could learn how to control your magic there, but you couldn't leave. Bad deal.
That changed when the rebellion started, but that's a pretty recent development.
