I see nothing to suggest any national movement whatsoever to ending or reducing the "pay to play" model, and/or encouraging kids to stay in soccer. There are some local efforts at the club levels to solicit funds for "scholarships" for players, but this just puts more burden on the other paying parents, and ultimately those funding sources will dry up (as paying parents eventually take off-ramps).
That said, it's unclear if the US has the national desire to fund soccer development as a priority either. We don't really fund any sports at the national level in the same way as other countries do.
But also, of course, this topic has been discussed extensively already on many other threads here, so nobody is likely to say anything new.
