I remember being assigned to read ‘The Jungle’ by Upton Sinclair and ‘Elmer Gantry’ by Sinclair Lewis way back in what is now called middle school. Admittedly, I often confused the two writers’ names, but I enjoyed the two books immensely. And, learned that our commerical (and religious) industries still need a lot of work. (That still hasn’t changed all that much in half a century, either.)
