What the article you've attached doesn't mention is that, in the specific case of the US teams, the women are bringing in more money than the men.There’s no ‘pay gap’ in professional football
The Women’s World Cup doesn’t generate anywhere near as much money as the men’s.
According to financial reports from the U.S. Soccer Federation reviewed by the Wall Street Journal, USWNT games generated more total revenue than the USMNT games from 2016 through 2018: $50.8 million in revenue vs. $49.9 million for the men.
They also generate higher TV ratings and sell more merchandise than the men.
So while it's true in other countries that the men's national teams bring in more money than the women, and it's true that the men's clubs teams bring in more money than the women's clubs, in the specific case of the US national teams, the women bring in more money than the men.
That's what the pay dispute for the USWNT is about. They're bringing in more money for the USSF and for Nike than the men with their national team appearances, but the USSF is paying them a fraction of what they're paying the men.
