You can easily see the difference in ball skills (passing and receiving, especially quick 1-2s and creativity) in tonight's game between Brazil/Columbia vs. the USA. I think it's from kids in those countries playing soccer all day as kids before they get into organized competition vs. in the US where everything is under adult supervision. The blog linked below talks about this.

There's been an awareness of a couple different problems with US youth soccer coaching that's now spanned a couple decades, at least. And there have been some efforts to address some of the issues. There's the issue of how the "best" clubs and teams are typically only available to kids of relatively well-off parents. And there's the issue of pressure to win versus develop.
Most of the phenomenal coaches associated with US Youth Soccer that I've met over the years understand and preach development over winning in youth soccer. But it's one thing to say and quite another to do. Combine the over-prevalence of so-called premiere soccer clubs with typical US parental attitudes and the pressure to win, even at early ages, becomes overwhelming. So fixing things here in the US has proven to be a tough row to hoe.
Parent's with money will seek out those teams with the best rankings for their kids. Rankings are based on winning. Teams of nine year-olds are being measured by rankings/winning. This is counterproductive to focusing on development and creativity and a love of the game at young ages. And it forces a style of coaching that is counterproductive to taking a young talented player and molding them into the best possible player they can be.
For example, in order to win at younger ages, coaches will spend far too much time on rote tactical and role instruction at the expense of individual skill development. This is totally backwards, totally inefficient because kids at young ages take much longer to learn tactics and roles than those same kids just a few years older would take. And worse, human brains are way better at developing individual ball skills when they're younger, but that precious time is being wasted on rote tactical instruction instead. So the kids wind up less naturally skilled w/the ball and with a bunch of often improperly onboarded tactical and role instruction (because the tactics and role instruction is compromised due to the young age).
Focusing on individual skills at young ages and then tactical instruction at older ages is vastly more efficient. Because what might take 30 hours at U10 will only take ~3 hours at U14 or 1 hour at U17. Meanwhile, although a 17 year old can work hard to develop their ball skills, they may well never quite attain the same level of instinctive brilliance they might've had they focused almost entirely on their individual skills with the ball, and a love of the ball, from the youngest ages. The way we're doing it actually hinders many players development.
Coaches I've spoken with over the years often know all this and don't want to focus on winning. But they're forced to do it in order to be competitive and keep the team's rankings high, keep the club's money-train flowing, and keep their jobs.
I remember the director of US Youth Soccer coaching in NJ ranting a bit about this at one of my licensing courses many years back. He seemed to think that having all these premiere clubs was harming US soccer. I was unsure back then. But it seemed a not unreasonable theory, and over the years, I've started to buy into it more and more. Now I'm a full-fledged believer.
First of all, there really aren't that many kids with truly elite talent, so parents are being basically scammed to some extent. For another thing, younger players should be having fun in games doing crazy stuff with a soccer ball and figuring out simple combination play all on their own through small sided games that make it instinctive. That makes the game way more fun, and it builds talent and awareness naturally and deeply.
They shouldn't be being screamed at to go here, then go there, then do this thing - which is kinda the opposite of how small group tactics should be taught anyway, requiring some coach to come along and correct that player's understanding later in life.
