There will always be people that will pay it , nothing more true.
I can never understand the question originally asked. This is a service industry , plain and simple , and within that reasoning the service is time and companionship.
So the level of that service and what is involved dictates the price. The providers i.e. the ladies , all have different ways of delivery this. And the other factor is that its a business , businesses survive based on return custom.
So as has been said it's really no ones business why the prices are what they are , it's up to the provider to dictate that , and what they provide for that is what you pay for.
Like all businesses they have to start somewhere and as they grow and get a good reputation so do the charges , if not maybe the demand is good enough.
You want longer ? fine pay for it.
My own business is a service business too. And the people I employ and provide along with myself , we charge for out time , and expertise , if people don't want it ? I don't loose sleep over it. I have a very good regular customer base , and long term contracts that I never have problems reviewing and re signing.
If people don't want to pay our rates ? There are plenty more fish in the sea.
You build you client base , based on your reputation and the standard of service you provide and the feeling the client gets of knowing that in their hands I know everything will be ok , and its money well spent.
Much like what the ladies provide.
Everyone is different it's what they are comfortable with charging , and what they hope to achieve financially.
Nobody has the right to question what people charge for their services. If they don't like it ? Go somewhere else.
This business has one difference. Its personal , its intimate , and the most important its fantasy
Your own worth dictates everything.
