Being a prostitute doesn't mean a woman is inferior. She is not forcing, or cheating anybody. She is clearly doing business, very honest, provides happiness, and gutsy unlike most of us (if she is not forced into it, which a significant percentage of prostitutes are). I wouldn't accept she is more intelligent than me, till I discuss issues with her. If she thinks better than me I would certainly accept she is better than me. The fact that she is a prostitute should not be held against her. She is earning her living like everyone of us are.
