OK.  You did not say "willing victim".  What you did say was "not all women are unwilling victims".  To me, "not unwilling" and "willing" amount to the same thing.....
I imagine that many young people hope to become rich and famous.  The thing is that those who are in control should not expect that dispensing sexual favors will be part of the employee's duties.  
And your last sentence -- well, the sad truth is that many careers require one to make moral compromises of one sort of another to get ahead (eg bankers who foreclose on homes).  Some of us are fortunate enough not to have been placed in that position, but I find it hard to judge those who are on the bottom rungs of the ladder who find themselves in the position of having to make those decisions. 
Although the sexual abuse situations may be complex, the fact is that it is one person who is holding all of the power; from my perspective, that is the person who is morally responsible.
