Haha. Totally nailed that: England. I'm still batting 1000%. Spain over here which is why I'm rolling my eyes (as most of the Continentals tend to do), but all in good fun. No malice intended, though a large part of the problems with US soccer stem from the wave of B level English soccer rejects that came over to the US in the 1990s and established the system. Thy country men are partially to blame for the mess over here (don't get me started on Mexico). So were you an English public school? As you are aware university admissions there are determined by exam performance, with respect to certain subjects. Here there is athletic recruitment which is a separate entry way into college, hence why the appeal of competitive sports to some families.
The "bought and sold" is a political statement about the effects of what the academies in Europe do. See below. I agree there's something limiting about short messages that doesn't cover all the nuance. I have been accused in the past of writing tomes over here, but this is why sometimes tomes are necessary. It's also not true that anyone can just play. My son is pen pals with a goalkeeper his age in the UK that had a youtube channel, HenrySavesAll. The channel details how the kid struggled to get an academy trial, ultimately got one, but did not get a place at his local academy and ultimately switched his focus to academics and decided to just play the English equivalent of rec as a field player. The difference between that and the US is that there is a D team for every player and there isn't some overall authority to handle sorting as there is in the US and UK....the leagues (MLS Next and somewhat ECNL excepted) are just ad hoc setups where the customers are the clubs and are just venues for the kids to play.
Thousands of players wash through the system every year, leaving behind shattered dreams of a professional career. Are clubs doing enough to look after them?

This is an American cultural thing called "puffery". It's why you have so many shack's selling what they claim to be the world's most famous or best burger. The score diminuation thing as stated before is a deliberate decision of US soccer at this age to minimize the American obsession with winning and the distorting effect it has on development.
The safeguards you ask for aren't possible. There were problems even with the old pro/rel system by Coast which ultimately led to it becoming the mess that it is. The only way those safeguards would be possible is if you had 1 authority in the US that controlled the placement of players in appropriate levels and controlled the various clubs (kind of like a giant AYSO United). That's simply not the political reality in the US. There is such a system, but it is limited to academy play, which again doesn't start until around age 11. You seem to be mourning the fact that unlike the rest of the world, the US does not have a true academy system.
If that's the experience you are looking for your kid, I'd echo the suggestions of those here on the boards. Club sports at this age is a waste of time. Get him with a trainer, play futsal, and have the ball at their feet non stop until the year before academy selections. otherwise, since you have residence anyway, if football really is going to be such a central part of your kids future, time to look at moving back to England. Your kid won't get what they need here, which is why so many American footballers are going over there to train (particularly those with dual nationality that can do it as a younger).
