I don't have any figures in front of me, but this could only be possible during a woman's World Cup year when the men's team doesn't have any major international tournaments to provide an income boost for that year.
Men's World Cup generates so much money that if you take each team's World Cup take and divide it by four, to annualize the income, the men's team has to make much, much more than the women's team per annum.
Sports is eat what you kill business. The women's team has won more games, but that just entitles them to a bigger slice of a much, much, much smaller pie.
If the women's team wants to be paid like the men's team, they have to start generating TV revenue like the men.
