The book is a masterpiece, and easy enough for teenagers but perfect for adults too. It starts with Frédéric Bastiat’s great insight of the Seen and Unseen, and in a single famous paragraph Hazlitt exhorts us to consider the long-run effects of an economic policy on everyone. Just reading this four-page lesson puts readers well ahead of most people! Each subsequent chapter is a short, devastating, stand alone lesson: debunking the broken window fallacy, demolishing public works and taxes, demystifying tariffs and “trade deficits,” destroying arguments for minimum wage and protectionism, and decrying state intervention at every turn. It’s a remarkable tour de force of less than 200 short pages.
