As someone who had both good and really bad times in schools, works in tech, and is considering it for our kids, some thoughts:
Never once did I want my kid to “not be around mediocre”, it’s the extremes I want to filter.
Part of the reason we’re considering private school is to avoid the bullies/wannabe gangbangers who don’t care if they end up in jail that made my own life miserable.
Similarly, our concern is with the other extreme, anxiety-ridden, high-expectations “has to change the world” is not what we want his social culture to be.
A group of kids that enjoy learning, understand the employee/entrepreneurial trade-off but may still opt for a 9-5 is what we’re after.
A friend of mine half-jokingly suggested “the cheapest private school” to balance this out, and actually seems like a half-decent solution.
Like with general life consequences, we want them to experience as much variance on their own while avoiding extreme swings with long-term negative repercussions (horrific injury, jail, dangerous drugs). This is just one facet among many for us.
There are private schools which have more and less competitive environments, it just depends. I'm not convinced that filtering by tuition cost will necessarily get you what you want, you'd want to research the individual school and talk to families and so on.
