One of the things that stands to kill all sports - soccer included - is travel ball, 7 on 7, and summer leagues.
Without getting preachy, there are a lot of families that are unwilling to commit the resources - time, money, etc. - to letting their kid go all out. It is incumbent on high school coaches to make it clear that they will not punish a kid for refusing to play travel ball. As families are relegated to rec leagues because they don't do this crazy travel stuff, those families are going to lose interest in high school sports, which could easily carry over into the college and pro leagues.
