men who have dynasty money and can blow like 10k for hour or 100k for a night with a girl get really little satisfaction out of buying a normal prostitute. It only becomes a little bit thrilling again when the woman you're taking and using is something most people could never have. A celeb, a top model or... a respectable, capable career woman who would never think of selling her body. Thus there is a lucrative market for prossies who can pretend to be these things, and it's worth the time to even complete a degree, spend time "in" an industry. Your price goes up like 20x
