Book excerpt: 'Why is there so much inequality?' Xenia asks her father, the world famous economist Yanis Varoufakis. Drawing on memories of her childhood and a variety of well-known tales - from Oedipus and Faust to Frankenstein and The Matrix - Varoufakis explains everything you need to know in order to understand why economics is the most important drama of our times. In answering his daughter's deceptively simple questions, Varoufakis disentangles our troubling world with remarkable clarity, while inspiring us to make it a better one.
