Kids don't actually learn much curriculum content (as opposed to social behavior) when at school. They do that when at home.

Poor kids' homes aren't conducive to learning. They lack the necessary materials, (undisturbed) space and time. Necessary social support for content learning is often absent.

Wondering about why money given to schools (used for the most part for administrative nonsense presumably) doesn't change outcomes much consequently appears to show a (class based?) detachment from respective realities?
