" Money is meaningless.” Waxillium perked up. “What?” “Only expectation has value as currency, Waxillium,” Uncle Edwarn said. “This coin is worth more than the others because people think it is. They expect it to be. The most important things in the world are worth only what people will pay for them. If you can raise someone’s expectation … if you can make them need something … that is the source of wealth. Owning things of value is secondary to creating things of value where none once existed. "
