Having a better salary than someone else doesn't make you more intelligent or skilled than them though. It's silly is to judge someone's intelligence or skill based on their opinion of value.
On the note of scale: I'd be happy with £40 for 15 minutes, but not £160 for an hour.
Of the 534 escorts in the North East(on Adultwork) there are only 15 with hour long incall rates as high as theirs. Several of these look to be webcam girls who don't actually escort, girls looking for SDs, and private gallery scammers.
I'm honestly struggling to understand how what you said makes sense to you.
During 60 years dealing with big business all over the world I found many who get paid a lot do so only because they're good at arse-licking their way to the top.
As for rates, it really depends what you pay for and how well you're doing financially.
For straight sex I find it hard to justify paying more than £120 an hour nowadays. For exotic variations - S & M, squirting and general filth - £150. I see two girls in Devon regularly and pay £250 for an hour of very imaginative stuff - whips, squirting etc.
For a well-known German porn star specialising in scat etc. I paid £450 for two hours and was delighted as she was amazingly imaginative. When I was briefly very rich I used to fly to Munich for that kind of thing with another well-known lady; can't afford the money or the time now.
I think most on here aren't interested in such exotic stuff and paying a girl £200 for an hour makes no sense.
