I have no problem with this... in fact, the women should probably be making more (and do, because of endorsements)
The market dictates salaries...
Women's Tennis > Men's Tennis = More money for women... and conversely:
WNBA<<<<<NBA = Men make way more
WUSA<<<<<MLS = Men make way more
LPGA<<PGA = Men make more
Women's Hockey<<<<<<NHL = Men make way more
Fact is, due to biology, most sports are better played by men, and in few instances where it can be comparable (tennis, curling), compensation should be equal. In the case of golf, where the top women can be around average male players, they should be paid approximately what that performance would garner in the PGA, and right now I think they make even more than that, cause of popularity, which is good.
