Who really creates wealth in our world? And how do we decide the value of what they do? In modern capitalism, value-extraction is rewarded more highly than value-creation: the productive process that drives a healthy economy and society. Yet, argues Mazzucato in this penetrating and passionate new book, if we are to reform capitalism we urgently need to rethink where wealth comes from. Will reignite a long-needed debate about the kind of world we really want to live in.
