The "rest of society in adult life" is a very different kettle of fish from a powerless child in a situation over which they have no control.
Childhood is a very precarious time - and we all want to do right by our youngsters during the one go they get at it. But we send them out of the door to be influenced by others, many of whom might have values we do not share, be poor at their jobs, be cruel peers etc. It is blooming tough.
I would have educated mine at home if it had been possible. Some of the influences they came under were not positive. For instance one DD was very bright - but the school she went to was so pushy that she came away thinking she was thick - they taught by humiliation. Another had some specific learning problems and was destroyed by the taunts of her teacher - we had to remove her from that school.
And another DD went to a school that was so bland and non-descript that she lost interest in most subjects. No firing up of the desire to learn there - mind you, who could blame them? - there were 1200 pupils!
We really have very little idea of what children are being subjected to when out of our orbit; and, whilst they need to have the corners knocked of them a bit, it needs to be at the right age and in the right place.
Schools can be difficult places for both staff and pupils - and children need to be under the influence of people who are not burnt out, exhausted and disillusioned by the system in which they are employed.
It is a bit of a lottery, and I for one felt very uncomfortable about subjecting my children to a system over which we had no control or influence. I wanted the best for them, but it was not to be had.
anyone else 'age proofing' their homes

Love it! We used to get tripe for the cat when I was little.
