Going with THE Franta's thoughts...
I've been to a few strip clubs on a few occasions (before someone chimes in, they were clubs with women dancing, not men :) ) and *believe me*, those girls were not being degraded...every single girl working there, had more common sense then any of the men attending the club. They had the hustle down to a science, and played just about every guy there like a fiddle. Whether the strippers were talking some chump into buying eight dollars shots, $20.00 T-Shirts, air dances, etc, the girls were more or less degrading the guys, by treating them like absolute morons. Personally, I always went to have some girl dry hump me for a few songs, but that's neither here nor there...
As far Playmates and porn stars go, I imagine it is the same thing. Just look at Hefner's "harem" of golddiggers. The instant that guy drops dead, they'll be collecting for services rendered...trust me.
Same thing with this story. The male customers may think that they are getting the best of the women, but the women will be laughing all the way to the bank...$10,000?!? Who is really degrading who here?
