Thought provoking post Easy which, as you mention, delves into a lot of different areas.
As far as price, the hobby is no different than any other economic transaction in that price influences value perception and higher dollar ladies are always going to be held to a higher standard.
Generally speaking however, after a certain dollar threshold, unique to each hobbyist is passed, the law of diminishing marginal utility will always set in whereby the additional pleasure derived from each additional dollar spent is deemed not to be worth the trade off.
These subjective dollar thresholds differ for each hobbyist individually. Collectively, they make up the market place. For some guys this means they feel there’s no reason to drop $500 when in their estimation, they can have an equally pleasurable experience for $300. For Eliot Spitzer, it might be the difference between $2k and $3k. And for Felix from backpage, perhaps it means he feels he can get off just as well for $40 vs. $50.
Everyone, be they purchasing widgets or hookers always seek to maximize marginal utility. If a hobby fairy were to award each gentleman on this board $2500 with the caveat that it had to be earmarked for expenditure on escorts, while they may be inclined to spend more than they would under normal circumstances, I suspect the guys who would elect to blow it all on a single visit would still be in the minority and that most would opt for multiple visits / multiple ladies.
It might be unfashionable to talk about money and nobody wants to be perceived as cheap but everyone always seeks to get the greatest bang for their buck, even if they do a poor job doing so.
With respect to ratings, context is always important for me since most gentlemen develop their own baselines which only have meaning when viewed as part of their review history’s framework; a respected reviewer’s score of 8 will certainly be more influential in an astute hobbyist’s decision making than the smitten newbie who awards the same lady a 10 or the asshole with an axe to grind who scores punitively just to be a dick
