Ayn Rand is the primary author of the book since she wrote most of the chapters. She also authored other books, such as Atlas Shrugged, the subject of Chapter 15. Capitalism, a non-fiction work, clearly expresses the author's political views. She states her views on various subjects in this book ranging from free markets to smear campaigns. This book allows Rand readers to learn the author's views on various economic and political subjects as she freely states her views and positions on various issues without having to do it within the framework of a story. Most of the chapter selections come from newsletters and articles which the author wrote or collected over the years. This is a much more direct and easy way for the reader to learn Rand's philosophy than to read her novels.
