First, you seem to be ignoring basic realities. At $150/hour, some guys might be able to justify it. But at $300, they might not. It might be viewed as a bit waste of money. How many times have you been with a provider, and you feel like you would have been better off staying home? I've had this happen. And it's way worse when the girl charged $200+, and downright depressing when she charged $300+
Second, there is buyer's remorse. You must have never spent your hobby money on a girl and been disappointed. This, no matter what you paid, strains credibility. But when you finally do pay $600 for a girl who lets you do anal, swallows, and whatever else you like to do... but who just doesn't click with you personally... you might experience this feeling.
"Couldn't I have spent my money with one of the other girls who were available?"
Buyer's remorse is more painful when the price is higher. When a girl only charges $150 (or less), and she's bad... oh well. Not ideal, but not the end of the world. You can go see another girl and have a great time.
Third, your basic point is that $ = quality, as evidenced by review ratings.
But you ignore the "buy-in" fallacy. People who buy Apple products swear they are better, even if it isn't objectively true. Even if they aren't faster, higher quality, more reliable, etc... But they are more expensive. And people feel like they MUST be better. Especially after they paid for it. Same reason people value a painting more, once they actually own it (look up the research on irrationality, by Dan Ariely).
So yeah, guys who pay to see top-shelf girls view those girls with the rosiest of rose-colored glasses. She might be every bit as great as the reviews say, but she could easily NOT be, and the fallacy, combined with the client's strong internal desire for the provider's approval, will push the review numbers up.
I actually value connection over perfection. I don't know if the shit you get up to with your ladies is based on the same kind of connection. I can't hate a girl and fuck her, no matter how hot she is. I have to really really connect with a girl, and money cannot guarantee that. I've said it before, and you just ignore that, so for you it must just be hard to connect with a girl when you are choking her to death with your cock. Maybe try talking to them and making them feel good?
In the end, no matter the connection, if I can't afford to see a girl 3 times a month, I can't. Doesn't matter how much I might want to.
It's not about being cheap. I don't try to see girls I am not prepared to pay fully. I don't ask girls to charge me less, or negotiate. I have been negotiated with, but it wasn't me saying "your rate is $200, and I've only got $175" or something. I don't know how any guy does that...
I don't tell you what to pay or who to see. But somehow, you can only see this issue from your rather narrow outlook. I've offered numerous reasons why your basic complaint isn't built on solid footing.
