Specifics are a useful starting point for getting to fundamentals; trying to learn abstracted stuff without having anything to tie it too tends to be a bit tricky. Even for adults, which is why "here's a novel to help illustrate what we mean by these things" is a thing (for example, The Phoenix Project). It's also why math tends to start with arithmetic and memorizing times tables, and only after that gets to more fundamental stuff like algebra and then calculus.
sadly, some folks disagree
these skills have enabled them to live a great life and they want the same for their children
i certainly can understand that, but i disagree with the approach
Starting vocational education so young feels like a slide back in time to the 19th century, except even then, apprenticeship usually began around 12-15 years old.
Teaching children specifics without fundamentals prepares them for the job market, not for life.
