Broken Money, by nostr:npub1a2cww4kn9wqte4ry70vyfwqyqvpswksna27rtxd8vty6c74era8sdcw83a is only one of two books that I have ever read that acknowledge the anthropological fact that the first known organized economies were built on debt-based ledgers. Money came later. The other book is "Debt: The First 5000 Years".
