Re: The story of "Maria" and "Roger"!
Well, in terms of how big-name tennis players actually make money, it really is about selling tennis racquets (and shoes, and other things). And Federer gets paid: 35+ million dollars per year, while Sharapova gets paid 21+ million dollars per year.
Five tournaments a year, women make as much as men. Four of those five tournaments make the men play an extra set or two or three. But the other 60+ tournaments, in which women play as much as men, the men make dramatically more money than women. And sponsors give the best male sponsor draws dramatically more money than women.
So for all the chauvinists out there, ask yourselves why women are stuck making 40% less per year than men for the same amount of work, and then ask yourselves if you think the prize money debate is unfair to men.
