This is a book written for the mass market written in a sensationalist style. If you are looking to learn about economics or are looking for facts proven by rigorous scientific study, this is not the book. However, what I liked about this book is its rogue approach of making almost heretic claims against established wisdom.
Whether you find the viewpoints the authors and collaborators of this book present to be believable or not, we do learn something important from reading this book: Conventional, established wisdom isn’t always gospel and needs to be challenged at appropriate times.
Parts of the book, especially the Chicago gang stories from the sociologist Sudhir Venkatesh are gripping like a novel. You will enjoy reading it. I recommend reading it.
