One of the issues is the federation was giving out per Diem differences for the two teams. Like the men needed more per day then the women. But based on all of the corruption on top down in FIFA, hoarding wages on something like per diem isn't unexpected
I think the revenues are from only home game ticket sales, when the US men's had a down year and missed the tournament completely. I think it was something like 50.3 to 49.9 million over that three year period. They also played more home games last year and generally play home games, while the US plays a lot of friendlies in Europe to help their foreign based players travel time in regards to club management. But Federations and Clubs have always been at odds over who/when can be called up.
