The USWNT have won four Women's World Cup titles (1991, 1999, 2015, and 2019), five Olympic gold medals (1996, 2004, 2008, 2012, and 2024), nine CONCACAF Women’s Championship titles, and one CONCACAF Women’s Gold Cup title. They dominated their sport for decades.
The USMNT has never reached the World Cup finals, and last reached the semifinals in 1930.
If you think those results merit calling the USMNT “better,” we have to agree to disagree. But yes, a men’s team that is middling earns more than a women’s team that is dominant. That does not make the men’s team better IMHO, just that they play in a league with larger viewership (mainly due to their competition, not their performance).
Market share of the league is a factor. But so are results of the specific team IMO. Should SEC football players be paid more NIL money than ACC players because more people watch SEC football? If so, the ACC is cooked so we might as well start looking for another landing spot.
