You can add Orwell to the list. His elite schools provided the foundation of his loathing of the English elite.
I am certainly glad I don't have to make these decisions in this era. It was extremely hard being a parent back in that other age of the US when there was still some pretense of liberal education. I had to watch my kid go out into a bad world and just trust him to be okay, fight the fights he had to fight and struggle with his struggles. There really was not much I could do.
