Female tennis players recently demanded prize money equal to the men, and got it.
If women athletes drew bigger crowds and sold more merchandise than the men, they would get paid more than the men. I feel certain that women gymnasts get better endorsement deals than the men. (Can you name a male gymnast? I can't.)
But they are less popular, play fewer games than men on average, and still draw the same pay. The average man must play more games in order to qualify for Wimbledon. PC gone amok:
Now, time spent on the game alone may not be a perfect measure of the value provided, but until something better comes up, I would say it is the one we should go by. Can you propose something better?
