Is there a difference if a woman "succumbed" to threats or if she saw granting sexual favors as an okay way to advance her career?  The problem is that sexual favors are a way to advance a career.  Take away that granting sexual favors as  "a part of the game", as Monica put it, then at least some women who don't want to buy advancement with sexual favors won't have to.  Make it dangerous, shameful for man or woman to play the career game with sex. 

Of course there are some women who willingly trade sexual favors for careers, wealth, the next drug fix.   There always have been and always will be women who will do that.  You are not discovering anything new.  Yes, women who do that help perpetuate the problem, but they are a small fraction of the problem of trading sex for gain.  It isn't always men who are the problem - just most of the time given the power imbalance in the world.  This problem can't be addressed now except by focusing on males who abuse their power for sex.
