That is a big issue; the women’s game is much slower, and the players are a lot less talented. I’ve watched a few of the games, and you see a lot more passes to nowhere (or outright to the other team) than you’d ever see in a men’s World Cup game. The difference in athletic ability is stark.
The 1999 victory was used to promote a women’s professional league (which folded shortly afterwards); I believe they attempted another one, and that folded as well. Unlike the WNBA (which is funded by wealth transfers from the NBA), there is little money in the men’s leagues in the US (MLS and NASL) - so there is nothing to prop up women’s soccer.
It doesn’t help that the US team looks like a gay pride event...
You mean men are bigger, stronger, faster, etc.? Stop the presses!
I have two soccer playing daughters. We get to several professional games a year, both men's and women's. (It's probably better for young girls to be watching the women's teams, because the games are different, and always will be, and the women are playing the game with which the girls can identify.) The men's and women's games are both enjoyable in and of themselves. I do not understand why some people think it has to be an adversarial or competitive comparison.
Point of view is probably important. A lot of people live in tv land, and that goes double for sports. They look at the professional or major college games in all sports, which become their sole point of reference. The perspective of participants, and parents, is very different. 99% of the soccer I watch is on the sidelines, watching my daughters play. By the time my older daughter was 13, she had graduated to playing real soccer, on a reasonably competitive team. If one can enjoy the game at that level, one can certainly enjoy the women's professional game as well.
Of course, I only watch games in any sport if I have a rooting interest. I'd rather watch a high school game where I know some of the players than two random professional teams. Cheer for the local team; cheer for the U.S. team. The U.S. women's national soccer team has always been among the best in the world. The U.S. men's team is a respectable second tier team (with two impressive wins this past week). If you can cheer for U.S. women sprinters, swimmers, gymnasts, and skaters in the Olympics, why do you find it difficult to cheer for the soccer players, who are also bringing home the gold?
The men are bigger and stronger in all sports. This doesn't mean that the women shouldn't play, or that people shouldn't recognize excellence. Building women's sports into a better paying proposition is a separate question, for another day.
