I obviously don’t know your specific situation but having brought up kids in a similar environment, I may be able to offer some possible explanation for what you are living through.

First, never underestimate the impact of your environment on your way of thinking. We all like to think we’re independent thinkers but really we’re much more influenced by the people we interact with than we could even realize. Once you have a kid, a lot of your social circle will consist of other parents so you will unconsciously absorb their values and motivations as well, including the desire to put your kids through all these hoops.

Second, many professional class parents believe that the key to future success lies in getting their kids into the right school. Hence, it’s never too early to start the kid on the path to great grades, background experiences, scholarships, etc. I’ve seen parents stress out about preschool enrollments because of the “advantages” these schools provided.

Lastly, this is very often the default path for parents. It’s just what you are supposed to do. Everything is set up in that direction. Defaults are powerful and govern our behavior much more than we all realize.

Final last point, the truth is no one knows what works when raising kids. For every story of a free-range kid becoming self-reliant, there’s a story of a latchkey kid that became a bum. Therefore, parents are generally risk-avoidant with their kids (there’s no do-overs) and tend to do “good” and “respectable” approaches in child rearing (like signing them up for sports, extra curriculars, etc)
