 Exploitation can also be harmful or mutually beneficial. Harmful exploitation involves an interaction that leaves the victim worse off than she was, and than she was entitled to be. The sort of exploitation involved in coercive sex trafficking, for instance, is harmful in this sense. But as we will see below, not all exploitation is harmful. Exploitation can also be mutually beneficial, where both parties walk away better off than they were ex ante. Most philosophers think that what makes such mutually beneficial interactions nevertheless exploitative is that they are, in some way, unfair.
