The rise in escort/masseur rates seems logical and inevitable considering the continuing rise of the cost-of-living expenses. I can't speak for other clients, but the continuing rise of the cost-of-living expenses has certainly curtailed (sharply) my participation in the "game."
It is unfortunate that there is not a discreet method for escorts to display their rates in their advertising. A clear statement of their rates in their ads would (should) stop, or at least decrease, calls from potential clients who are either not prepared to or are unwilling to meet their price point(s).
