Yeah I've pondered this before. I don't think its much different than politics. It's not that Politicians just so happen to also have a larger than average pedo percentage, it's that it's a requirement in order to be selected as a possible candidate for the position. There must be a fatal flaw that can be manipulated in the person before they can be approved for the spot. Otherwise they can't "trust" them meaning they must be compromised for blackmail.
Same for Hollywood. Music, etc.
