I enjoyed Dillow's book very much. It is a consistent and creative approach to the central question, and it is a pleasure to read a book where the author is so clearly engaged with, and passionate about, the subject.
My only caveat would concern the book's intended audience. For an interested layperson, the pitch is perfect: the book is an engaging whistlestop tour through economics, history, philosophy, politics, and much besides. However, I suspect the academic reader will find the occasionally scattergun approach frustrating (the chapters have, according to the preface, arisen fairly independently, and can be read in any order, which slightly disrupts the flow of the argument). In addition, Dillow brushes over some fairly major areas of academic debate - necessary, but occasionally unsatisfying.
Overall, this is an excellent introduction for those frustrated with the current turn of political discourse, and provides a good springboard for further reading for those more engaged with the topic.
