Bhaskar Sunkara was pivotal in managing this whole process, from the initial pamphlets on which this book is based to the ultimate product. His unique combination of substantive knowledge and production skills contributed immensely to the project. A large number of PhD students and activists read the manuscript and made very valuable suggestions. I am especially grateful to Niall Reddy and Neal Meyer for their suggestions. As always, Jeff Goodwin and Nivedita Majumdar read everything and helped me, not just with their feedback but also their encouragement. And finally, Asher Dupuy-Spencer was a superb editor, managing the production process with great skill and also providing some very important suggestions for the manuscript. My thanks to you all, and to the small army of well-wishers and supporters who have used the earlier versions of this book.
