Yeah, pushing kids may not always work out for kids. I used those examples to show it's possible for some kids to get advantages. That's also the reason I kept quantifying the examples with "if they are interested/talented" and etc. Maybe a reversed example is better: some kids could've stood out but didn't because they didn't have the edge of being in those camps/tutoring schools. I'm already seeing such trend: kids are in arm race of taking as many APs as possible. Kids rush to STEM contests, and etc. Schools can take out challenges, but the competitions won't stop simply because top-quality education is a scarce resource.
