Wgs` prices have nothing to do with what is justifiable - thy are governed entirely by two factors:-
1. How badly you want to fuck a girl, and
2. How badly she wants (needs) your cash
Your suggestion appears to be that punters should form a Union, presumably with a view to strike action, withholding our custom or whatever to bring them to heel and force them to reduce their prices. Unfortunately, you are completely ignoring (male) human nature, and there`s as much chance of a punter who has cash in his pocket but hasn`t had a shag for a month joining the strike or go slow, as there is of the wg cutting her price to oblige him.
If enough punters did hold back, however, all that would happen is that the lower quality girls with the smallest client bases would simply pack up and drift away, and the remaining reduced number of wgs would keep managing until the sex-deprived punters could hold out no longer, and would then have so much new business that they could UP the prices and get away with it.
I think it's this. WGs are selling a commodity, it just happens to be sexual services. According to the Labour Theory of Value, the value of any commodity is determined by the socially necessary (ie average) labour time needed for it's production. So in the case of a WG's labour power (her ability to keep working) it's her expenses and lifestyle costs.
I don't think there's any point in a punters' strike. According to the LTV, supply and demand does come into it in determining price
, but price still fluctuates around value, the money the WG needs to make. If she doesn't make what she needs to she'll quit. (If supply and demand was all there was to it, when they were equal, the price of the punt would be £0.)
The LTV explains why the cost of punting has come down in real terms. Since the collapse of the Iron Curtain, there's been immigration by EE WGs, who generally don't need to make as much money e.g. if they're sending money back home to support families, the cost of living is less compared to British WGs childcare costs ecc.
I could be wrong! Obviously the LTV doesn't explain phenomena like Miss Sexmachine for example who has a low price but looks hot but high maintenance.
