I think they explained the situation. I do think considering his background, the “early cherry-pick” and “weed out” process is common among Asian and east European countries, so I get where he is coming from, but it is an entirely different system here. The private clubs enables mass participation for kids with a variety of goals and trajectories, versus kids are picked to be successful for elite. In the US, we also don’t have the affordable integrated “sports schools” or municipal teams that funnel as the pipeline. Yes, in these countries, you gotta start and train hard early on, and yes if your goal is making the national team by 13-14, and peak during the Olympic cycle. Burnout, injuries and short athletic life are not among the concerns. There are pros and cons in each. They are just simply not the same system.
