These chicks who claim to get zillions of dollars for blowing rich guys are simply blowing hot air.
If you take an approximate income needed to justify spending some silly amount on a hooker, you'll find its a limited sub-set of guys who can afford it to begin with. Then factor out the guys who find chicks who will blow them for free, just to hang out with rich guys, guys who dont cheat, guys who are gay, etc etc, its a very small subset of guys.
These chicks try to create a marketing buzz and charge these rates hoping to hit the lottery - it rarely happens. But when it does, they all talk about it and keep hoping they will be the next chick to get overpaid.
Consider that the average salary in NYC is under $40,000 a year, the subset of women who would supply sex for the dollar amounts being mentioned wildly exceeds the demand for the service at that pricepoint.
Lets just say, that you can do much better, for much less.
