Jim, it may not be a ligitimate business, but it's a business after all, and like all businesses the client should be king, the client is what your business exists on, if you have a product to offer (sex and being good at it), people will pay for it, that doesn't make it wrong, that doesn't make you some sort of rascal, ne'er do well, it just makes you a guy who mightn't have the personality, looks whatever to go out and meet a girl, or want the complications of meeting a girl when you're married with a family, we all have needs after all and like electricity, food, water some out there consume more than others.
I may be wrong but from what I infer from your post is that you label or judge all punters/escorts as low lifes (may be a bit harsh) baseball cap/addidas tracksuit wearing, opportunist howya's and also judge punting and prostitutes (let's not mince words here) as an immoral illegitimate exercise, then again it is the oldest business on the planet.
Not having a go at you or anything, I'm afraid of 2x4s, specially when I'm not armed with one, never liked carpentry
[edit] also, they're making a damn lot of money out of it, tax free I might add, undisclosable, where for every €150 we hand over we've to earn €200 or so.[/edit]
