If the women bring in more revenue, than they should be paid more. I think everyone can agree on that.
I do contend, however, that the women's soccer team is more popular than the men's team here in the US. Some people even going so far as to say they are infinitely more popular. I would say they are about equal. Let's look at the recent World Cup for each as an example.
Yes, it is true that the Women's World Cup final had higher viewer numbers than the highest US men's game. But a.) it was the final and b.) it was on FOX, which is a free OTA channel. The highest rated US men's game was on ESPN, a cable station and it was a first round match. I have no doubt that if the men had made it to the final and it was aired on ABC, it would have equaled or topped the women's number.
Not to mention, the US men regularly pull better ratings in their friendlies and other assorted competitive matches than the women. The women are more competitive in their big events and people love watching big events, so they pull in some great numbers during those and that skews the numbers and people's perception. But I don't think that means they are more popular than the men's team.
EDIT: Some numbers to back up that last paragraph. Ratings for the most recent men's and women's games:
USMNT vs Guatemala (WC18 qualifier), ESPN2: 954k viewers
USWNT vs Ireland (Intl. friendly), FS1: 268k viewers
