While I am repulsed by the concept of exchanging sex for film roles, I feel the problem lies more with the system that allows this practice to sustain. If there was an equal playing field and opportunities to advance your career through auditions, maybe outsiders wouldn't be pushed to place themselves in these compromising situations to further their career aspirations.
Nepotism has its set of cons as well. As a fan of BW, I dislike seeing the misuse of familial connections by talent-less nobodies like the new crop of stars. They are not entitled to a career in films just because they were born into a film family.
