Club Youth Soccer in America is mostly a privileged activity for suburban families that can afford the high cost(s)
Youth soccer has a big diversity problem:

No body here is really poor and the rich people don't normally care for youth sports unless there kid is playing and they are trying to pull some strings or bulid these "super" teams.
Suburban youth soccer is most popular at what ages U10-U12? Kids love to play, learn the game, develop skills and they around the teenage years the numbers drop off dramatically and they stop playing and forget and soccer until they have kids and everything starts over again. Almost like a right of passage.
Kids have to love the game to continue to play, parents, coaches, and the current system we have does'nt help becuase we are don't foster the love the game, too much structure, playing to win, "elite" teams, division of leagues, etc. where soccer becomes a caste like system. We need a unified vision and for these orgs, clubs, etc to share and get along better on the same page.
What clubs or orgs (CS, usYS, usclub) need to do is more outreach and include the non-affiliated clubs and players that can't afford to play currently.
The MLS teams can do a better job of this also, like LAFC recently did with there ~ 50 non-affiliated team tournament at Bell Gardens this past weekend.
This takes $ and some people who are ranking in the big $ would have to step back for the greater good, for example every CS tourney could contribute 15% of the profits or off those ~ 100K "salaries" for the director(s) to go toward outreach programs or getting more kids involved.
