Actually, the more that I think of it, even though most people in their right mind would never pay this much money, the more that I think that she's doing it the right way by creating demand. Think of the average crack whore doing anything possible for 20 bucks or whatever.
Demoralizing? Certainly. Is she great business woman? You bet. Whoever has this type of cash to spend is going to be pretty affluent. Let's face it, sex has always sold well--be that scantily clad women in music or just the nature of the "world's oldest profession". I'm not saying that it's right, but guys have always been willing to pay to look at a little leg or cleavage and some capacity (strippers, Playboy, etc), and as long as time has existed, there have been professional ladies and there's been the men that are willing to pay for them.
If this were my mom or sister, I may be carrying a different tune though. It is an interesting scenario--there has been far worse things that people have done for far less money. In the end, it's only sex.
