Hey, I work in entertainment where the number two rule is (the number one rule is when do we eat) Sex Sells. If its not selling, add more sex. We have topless bars, topless car washes, topless coffee houses in the US, because we love selling with sex.* Heck, if I thought that Live Nude Girls would sell more tickets to the shows, you bet we'd have them > Carmen Electra and the Pussycat Dolls opening for Jane's Addiction - sure!
And people tend to so marginalize working girls. I know the ones out on the streets look like 53 by the time they hit 26, but the ones in the suites are doing much better.
And hey, I do so love doing Art and all that. But Slightly Stoopid, Killswitch Engage, & Insane Clown Posse and the rest of that crap pays just as much money as Art does.
We're making music for money, records for bucks. And that's prostitution in a way. Years ago now the London Symphony backed up Procol Harum or Deep Purple or some such band and I was listening to some fool yammer on about 'how that proves that Band X has real talent and should be taken seriously because if they we're not good the LSO wouldn't play with them, yadda, yadda, yadda.' And my friend, a professional musician turned to him and said: "The LSO is just a bunch of whores, you write the check, they'll play whatever you want." And that's true. Had nothing to do with the music, had everything to do with the check. So, they prostitute themselves, play that crap, and cash the check. Just like we all do.
* - don't try to sell sex though, that's against the law. Here, you'll love this, because it's true (I'm not creative enough to make this stuff up). If I were to say "Hey Jenny, how about we hop upon the couch of Eros and I'll give you $100 for a fifty/fifty." That would be against the law, because that is prostitution. But.... BUT, if I said "Hey Jenny, what's say you give me a fifty/fifty and I'll film it and I'll pay you $100." Hey, now it's art, now its commerce, now it's legal. So weird. So, just film all your professional encounters, that way it's not prostitution anymore.
