If it’s really that eye-opening is debatable I would say. As another user has posted it already, this is a more realistic scenario: https://www.theguardian.com/books/2020/may/09/the-real-lord-of-the-flies-what-happened-when-six-boys-were-shipwrecked-for-15-months

Edit: I am not saying it’s not a good book. I enjoyed reading it myself. I just don’t like the picture it paints of society and the conclusions people draw from it.
