Tennis and Gender

I just caught an article in the NYTimes that says, "For the first time, the women's champion and men's champion will be paid equally" at the French Open. At first glance, that seems like "Yeah, sure, that's how it should be, equal pay." But: in Grand Slams, the women's game is best 2 out of 3 sets, the men's game is best 3 out of 5. So the men have to work a lot harder to get the same dough. The minimum number of sets for men equals the max for women. Also, because the women's game doesn't require the same endurance or the same amount of time, many of the women that play singles will also play doubles, which means they can make more money than the men in the tournament.
I've read about a number of women players demanding equal pay, but they never seem to demand equal play! Why not? Make the prizes equal and change the grand slams to best 2 of 3 or to best 3 of 5 (3 of 5 is my fave, but I like games of stamina) for all players. Until that happens, I don't see how there is equality.
Go ahead and make a comment, if you like. I'm up for a debate.
