Equal pay for equal work. Sounds like a no-brainer, right?
In sports, there's never been a gender gap between men and women. It's always been more like a chasm.
Take golf. South Korea's Inbee Park is the leading money-winner on the LPGA Tour with $1.42 million in earnings this year. Two other women have also made more than $1 million in 2015.
Meanwhile, Masters and U.S. Open champion Jordan Spieth has made more than five times as much on the PGA Tour, in which 76 men have already topped $1 million.
WNBA players made an average of $75,000 in 2014. In the NBA, the average was $4.5 million.
But that's equality compared to World Cup soccer.
