I'm no economics expert. But one thing I have noticed is that since Covid there has been a significant spike in the cost of living. I can't think of anything that hasn't significantly increased in price over the past few years. From electricity, rents, groceries, mortgages,fuel etc.
I have had to raise my prices for my services in my business to partially curb the effects of the increase in costs to myself. The way I look at it is that Shops are facing the same dilemma and so are the working girls. They are not immune to the effects of inflation because its the "sex industry". Obviously the cost to run a shop today is significantly higher than it what it was in 2020. Your local Thai restaurant isn't dropping their prices even if business hasn't been so good lately. Its the opposite, they have increased their prices to meet the increase in costs.

As a good mate of mine would say back in the day when we were fucking streetwalking WLs up at the Cross "wank wank money in the bank"
