I didn't grow up in so called Amerika, but I learnt Emperor's New Clothes in school. We learnt it in grade 7, when some students complained that they were too old for fairy tales. After seeing "the Emperor has no clothes" many times in the past year or two, I think it makes some more sense why we learnt this story much later than other fairy tale stories in school in retrospect. It's not like Snow White and Sleeping Beauty, as it's an actual social critique still relevant today.
