Almost as soon as the US Women’s National Team sealed their fourth World Cup title with a 2-0 victory over the Netherlands, a chant of “equal pay” spread through out the stadium in France. On Twitter, the #PayThem and #PayTheWomen hashtags started trending as well, as viewers and fans protested the pay disparity between the men’s and women’s teams.

As has been widely noted, the USWNT will receive about $250,000 each for their World Cup victory and participation in public appearances. If the men’s team won a World Cup, they’d earn about $1M each for their victory, because of the way prize money is structured.

Pay structures for the USWNT vs the USMNT are a complicated mess and depend on bonuses and club salaries as well as revenue generated. There are a lot of layers behind who gets paid what and why, but it’s becoming more clear that the women are the bigger stars, which invites more public scrutiny into why they overall earn a lot less.

The fight for equal pay has been raging for some time, and 28 women from the 2015 USWNT, including Alex Morgan and Megan Rapinoe, are leading the charge against the US Soccer Federation.

Per the Guardian:

The women have made the legal case that total compensation for the men is higher, even with the salaries the women earn, because the men’s bonuses are so much larger. In that sense, the ongoing Women’s World Cup offers a glaring look at just how skewed the bonuses can be in favor of the men.

Following an initial lawsuit in 2016, the USWNT players filed a federal lawsuit against US Soccer in March, alleging “institutional gender discrimination.” In their defense, US Soccer says the pay disparity is not about sexism, but about business reasons and argues that the players have a fundamental misunderstanding the issues.

Again, per SB Nation, US Soccer’s argument is that the women “… receive fundamentally different pay structures for performing different work under their separate collective bargaining agreements that require different obligations and responsibilities.”

With their fourth World Cup title in hand and the USWNT’s popularity at an all time high, Megan Rapinoe weighed in on what all that means for their equal pay fight.

“Well it’s not good for them is it?,” she told reporters. “Obviously, it’s huge. I think we’ve been a little shy to say that, putting pressure on ourselves, because I think we have a case no matter what, but this just sort of blows it out of the water. It’s like, is it even about that anymore? Or is just about doing the right thing? The federation is in a unique position to kind of ride this wave of good fortune and get on board and hopefully set things right for the future.”

While the legal battle is expected to last for some time, it’s becoming clearer and clearer, especially in the court of public opinion, that at they very least, the women deserve to be paid more than what they’re getting now.

“It certainly should be more,” Rapinoe said. “I think there needs to be a big invest made in the women’s game. God forbid, for once, we be overpaid.”
