The main problem with Women’s Soccer is Demand. I don’t see an increase of spectators, thereby an increase in revenue coming anytime, especially now.
Moral of the Story: Shut up and perform. Don’t tick off half of your potential audience. (ala Michael Jordan - Dolly Parton School of Entertainers)
Market forces should dictate wages. The women simply do not generate the revenue that the men do. To be paid on par with the men, the soccer enterprise would lose money, unless it was subsidized. If it was subsidized, it would then draw money from some other, potentially productive activity. Not exactly the best way to run an efficient economy.
