You can draw that line anywhere, just pick a number and say that is "so much." Why pay $200, when you can pay $100, or $400 when you can pay $300, or $600, when you can pay $400, or... It never ends.
So, Magnum, why do you pay twice as much as you could pay? Why not only do half hours at an AMP?
Really, there is no "reason" to pay more, pay less, or pay anything. How do you choose a lady? Why do you choose a lady? The reasons are the same at any price point, and the Sultan's answer - because he can - is true, not a joke.
I assume we all start with some sort of budget, whether it is what we can afford, what we want to pay, what we can sneak past the SO, or whatever. Then we look at the universe of ladies that fit our budget and choose one who turns us on. Or maybe it goes the opposite way, as one poster mentioned here, and we see a lady who looks very good and then try to figure out (if it is a stretch for the budget) how we find the money to pay for her time.
Guys pay a lot because they can and the lady looks good to them, the first time, and then they come back because they had a good time. That is exactly the same as at any price point. The actual number of dollars, and what those dollars mean to each of us, are just as subjective as the pleasure the lady gives them. A lot of money to me may be nothing at all to you, or the opposite.
Next question - oh, wait, I know that one, it will be "is a $600 lady definitely better than a $300 lady (or fill in whatever dollar amounts you want)?". That one is easier - there is no general answer, and if you want to compare two specific ladies, no one else can tell you what the value of each will be for you - go sample, consider and post your reviews so we can know what you think.
There are general differences between experiences offered by providers at different price points, but they are only general. Exceptions are the rule. Ladies get more money because they want to, figure out how to, and are prepared to do what they have to do in order to get that money. And because they can, by which I mean that they possess certain skills and attributes that make this possible, not because some sucker will pay them.
This reminds me of a little fact I love, and it relates a little to this. Over the years there have been a lot of surveys taken, asking people to define what it means to be rich. The results have been consistent, both over the years and for people with every amount of assets from $500 to $5 billion - no one ever believes they are rich, and they always define being rich as having twice as much money as they have. My guess is that the real question here is - why pay to see expensive providers, and the real answer, no matter how much you spend, is that no one pays to see expensive providers, we all pay a fair price to see wonderful providers.
But I am guessing that is not the answer you want. The answer you want is that people pay so much more than you do because they are idiots who do not understand the ultimate wisdom of your approach to the hobby, or maybe you want to be told that if you spend the money on one of these premium providers you will have a life changing experience that will turn you away from BP girls forever. Either or both may be true, but only you can say.
Me, like everyone else, I never pay "so much."
