btw- We've been told that U.S. soccer is finally here for about 30 years. Clint Dempsey, Landon Donovan, Freddy Adu, Cobi Jones, Alexi Lalas, etc, etc. They've all been chronic underachievers.
I mean, Team USA (men's) is ranked 15th in the world, and we've been in the top-10 in the last year. Their all-time best ranking was 4th in the world. We've got an established domestic league. Soccer has surpassed the NHL in viewership. So, the team itself probably is "here".
I was going to make the case that men's soccer isn't a top priority for US high schools/universities. The fact that soccer is now more popular than hockey makes the USMNT's lack of success even more noteworthy.
When I look at the rankings, the U.S. is situated next to countries that are much smaller and have less money. Colombia, Wales, Sweden, and Senegal. The USMNT's best finish was 3rd place, and that was in 1930. The U.S. has unbelievable infrastructure for sports on a relative basis. Despite the money that has been put into developmental soccer, we're still a second tier country on a competitive basis (not to be confused with $). Reminds me of the Karl Malone/Gary Payton Lakers.
As a former lacrosse player, I've heard the same logic about this sport. "Just wait, it will get better". I'm still waiting.
My point: USMNT is 2nd tier, while USWNT is 1st tier. I think your concern with profit sharing would hold more water if it was the other way around.
