When I saw the blurb about a book from the 1930s being the only greatest book by a living author at the time, I clicked and to my surprise it was a book I have had in my library for many years, Tawney’s Acquisitive Society. I have to agree it is a great book and would like to suggest a companion book (not in the sense of their commonalities, but in the sense that a reader who liked one would like the other) — Homo Ludens, by Johann Huizinga (playful man I think is a decent translation).
