Fwiw, that's just commercially packaged nostalgia which is mostly the good (and often materialistic) part and forgets absolutely of the rest.

Our brains do that to us and I find it positive to have a nice fantasy world to escape to but definitely not to be mixed up with the reality of things.

OTOH being able to ride off into the bush with your mates and build tree houses and whatever and "be home when the street lights come on", have no phone, &c. was very different to the world we brought our kids up in.
