The value of something is what people will pay for it.
If you’re happy paying $300 for something, go for it.
If you’re happy paying $200 for something, go for it.
If you’re happy paying $100 for something, go for it.
If women are charging $400 for 30-60 minutes of fun and everyone starts paying that price then everyone’s price will start going up.
If they start charging $400 and no one pays that, they will lower the price.
If a woman can get $400-$500 a client, that’s her prerogative! Some woman can and some are worth it.
