Over the past fifty years, the way we value what is 'good' and 'right' has changed dramatically. Behaviour 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 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 seeped into our decision-making and, indeed, almost all aspects of our lives.
