Except that our vocabulary was at a 3rd grade level, and we had no concept of compound sentences or metaphors or what an analogy was. I've never met an elementary school student who could write at the chess level. They're all down at Tic Tac Toe complexity.

I said nothing about vocabulary or poetry. And many, many people, especially those who live in oral cultures, have elaborate vocabularies and sophisticated poetic skills, without any formal schooling.
