The problem is that as usual, you cannot demand women are paid the same when there isn't the same interest. It's absurd to state that women footballers should be paid the same as men given the levels of interest. Women's golf is the same. Modelling is the same. This is not the same as someone getting paid less for the same job, it's not even a job.
However as I said on the other thread, Djokovic has put his foot in it here, Federer and Nadal are really the ones that draw the most attention on the men's tour, i think the reason the men's final in the US Open a couple of years ago got less viewers than the women's one is because none of the "big 4" men were in it. So on that basis alone, Djokovic would have to agree that the prize money should be shared based on demand for the game, he would get less than federer or nadal, and his male ATP colleagues would get less that Serena for example.
If it's unfair that women get paid a share of prize money based on the fact Federer is at the tournament, then how is it fair that David Goffin gets paid prize money based on that fact ?
Jilly the men are better argument isn't absurd. There is no question that top male athletes are far better than top women, if there was no segregation in tennis, there would be no women in the top 200 and hardly any in the top 1000. The attitude that women are just not as good is sadly hard to argue against when it comes to sports where the faster and stronger you are, the more successful you will be.
I would be interested to know what ideas people have about this, but I think that the word "women" in sports is used as an asterisk, i.e. not the best at it, just the best women.
