Simple fix: require anyone buying a ticket for men’s soccer to buy one for women’s, and any marketing for men’s to include women’s.
Of course it would be against women to require the opposite.
Actually, for the US Soccer Federation (or whatever they call themselves), the women’s team brought in $50M vs $49M for the men’s team. This deflates the claims in this article.
Women’s soccer will soon enough be played by mostly men identifying as women, anyway, so “equal pay” is probably near moot.
