Paul Krugman comenta los libros que le sirvieron de inspiración y reproduce la siguiente cita anónima:
“There’s an age when boys read one of two books. Either they read Ayn Rand or they read Tolkien’s Lord of the Rings. One of these books leaves you with no grasp on reality and a deeply warped sense of fantasy in place of real life. The other one is about hobbits and orcs.”
