I cannot know what was in mr Kraft's head or heart. But I can speculate given what I know of the situation, and human nature, which is all any of us can do really, unless, minimus, you're a close companion and part of Mr. Krafts brain trust, in which case I will happily concede to your take on the matter.
Why would multiple men, with tremendous wealth, all be frequenting small, insignificant massage parlors, spending a pittance, just for a happy ending? Really? That innocent? Any of these guys could purchase any prostitute anywhere in the world, and pay them to perform any sex act they wish, anywhere they wish to have it, at any time, literally millions of times over. When you have that much power, it is no longer a challenge. It all can easily become vanilla. This is how and why some of the filthy rich can, and sometimes do, become involved in shady and sinister things, that leaves the rest of us in the peanut gallery scratching our heads, thinking, how could someone with so much money be so stupid as to get themselves into this situation, or get caught. The fact that there are multiple wealthy men involved leads me to speculate that they knew what was going on. As I stated before, I have no problems with people engaging in sex for money, as long as every one is a consenting adult. But, if we are to believe the story, the women involved were not. They were sex slaves. And I'm sorry, but these guys knew it. There's really no other plausible reason (imo. there, is that better, minimus?) for them to be involved. I guess we'll see what the outcome is. Perhaps mr. Kraft is an innocent party in all of this. Maybe he just innocently wandered into one of these establishments simply in search of a massage, and nothing more.
