Interesting article in Business Insider about the pay disparity. Apparently, men's and women's tennis players make about the same amount of money because they play their big tournaments at the same time: https://www.businessinsider.com/womens-soccer-players-footballers-equal-pay-fifa-world-cup-2019-7 "While tennis still has a pay gap at smaller tournaments, the women have achieved equal pay at the biggest events by playing the four Grand Slam tournaments with the men. With the major sources of revenue (broadcast rights, advertising, ticket sales) pooled together, it is nearly impossible to say if the men or women are generating a larger share of the pie." The big difference in revenue comes during the World Cup which is run by FIFA, not the USSF. "The entire purse for the 2019 Women's World Cup was $30 million, with the winning country receiving $4 million. In contrast, FIFA's purse for the men's 2018 World Cup was $400 million, with the champions receiving $38 million, more than the entire purse at the Women's World Cup. If the women were to play alongside the men in a single World Cup every four years, there would no longer be a gap in revenue generated by the women and the men, as they would be creating one larger pool. And if that argument goes away, so does a large chunk of the pay gap."
