In a 1940 Massachusetts public school, my blue collar grandfather was required to take Latin, immersive French, and was graded on handwriting. Latin plus a foreign language like Mandarin, Hindi, or Spanish should be the table stakes minimum standard. English composition, creative writing, and reading classics should also be nonnegotiable essential requirements too.
I have a book that says it's intended as a science book focusing on biology for around elementary aged students, it's from the 1890s and the material is something I'd expect high schoolers to start learning not 4th graders!
I was blown away by how... retarded... my reading comprehension and skills really are, when I recently opened Charles Dickens' "Bleak House," reading just the first couple of pages in! Yet I am even more deeply troubled that I am above the median.
