Isn't the biggest factor on how much players are paid is how much revenue is generated?

Yes it is, American idiots can't seem to understand simple facts. That's why this pay issue is only an issue in America not any other country.

To some extent. The English premier league gets massive revenue from TV rights and sponsorships, but the top teams are still bankrolled by billionaires.

Even if you go off percentage of revenue the women are underpaid.

The US Olympic Committee, a non-profit organization formed to promote US prowess in the Olympics, pays US Olympians a set fee for every Olympic medal they win. Those USOC payments are based only on whether the medal is gold, sliver, or bronze. The USOC doesn't alter those fees based on how much revenue a sport generates, or upon the gender of the athlete.

Contrast that to the US Soccer Federation, which pays female athletes in the World Cup far less than male players. The USSF is also a non-profit, and about 52% of all registered soccer players in the US are female. Consequently, registration fees from female players provide about half of the USSF operating budget. On top of that, compare the accomplishments of the WNT to the MNT over the course of the last 30 years. Its clear the women are being shortchanged. while doing far better than the men on the pitch.

That might be true for a for-profit corporation, but US Soccer is a non-profit 501(c)(3) corp that is not only the official FIFA governing body of soccer in the US, but also is responsible for promoting recreational and amateur soccer for all ages and all genders. US Women's soccer continued success in the world cup and Olympics keeps girls and young women attracted to the sport (which is very close to 50-50 male/female at the youth level), showcases the sport on the national and world stage, and brings in revenue for sponsoring companies like Fox, who are televising the games this year.

Men's soccer hasn't come close to the Women's team in comparative play at the world level. The US men did not even make the 2018 World Cup and the highest Men's scorer (Donovan) has only scored 5 goals in all the World Cups he played in, where Megan Rapinoe has done that already in this match and historically 7 women have each scored 8 or more goals their world cup history (and the women have only been playing since 1991). The US Women have made it to semi-finals of every World Cup held since 1991 (placing 3 or better) and won 3 of them. The US Men have been competing for the world cup since 1930 and the closest they have come is 3rd in 1930 and 8th in 2002 (not even qualifying in 2018).
