Over the past 50 years, the way we value what is "good" and "right" has changed dramatically. Behavior that to our grandparents' generation might have seemed stupid, harmful or simply wicked now seems rational, natural, woven into the very logic of things. And, asserts Jonathan Aldred in this revelatory new book, it's economics that's to blame. Licence to be Bad tells the story of how a group of economics theorists changed our world, and how a handful of key ideas, from free-riding to Nudge, seeped into our decision-making and, indeed, almost all aspects of our lives. Aldred reveals the extraordinary hold of economics on our morals and values. Economics has corrupted us. But if this hidden transformation is so recent, it can be reversed. Licence to be Bad shows us where to begin.
