I mean, prostitutes are not scum or something like that. They just do their job. Quite an honorable one, too. And as long as there are buyers, there will always be someone who sells. And let's be honest: Everybody would do that, it just depends on the price. Maybe not for USD 35 000 (even though that's already quite a lot of money!), but for other things. *shrugs*
But I guess that's just my way of seeing the world.
