I guess if I was told I had to suck a guy off or forever be ruined in the industry I was currently in, I'd hit the road. I was asked to do some sketchy things with money by a manager as a teenager and told him no and if he asked again I'd walk. Not that I approve of what anyone did, just stating the fact that you always have the option to walk, just like buying a car. I understand that some people don't feel they have that option, what I don't understand is why they feel that way. I guess they wanted to be in that industry that bad? I just don't get it myself.
I mean, its understandable. Millions of people dream of being famous. A large number of those have enough talent to handle a role. But there's only so many spots and its completely subjective. Would you trade an hour (or less) of something you don't enjoy for your dream? Especially if that dream could lead to an extremely lucrative career? Maybe you wouldnt, but a lot of people would. Now its obviously wrong for the person with the power to be exploiting their position to make that 'offer' but its easy to understand why it works and why many would accept.
Hell, there are probably some very famous people who are on the other side of this- people who paid that 'price' and moved their way up through the ranks to fame
