"The Benefit of Religion: An Essay on Economic Interpretation" is a thought-provoking work about religion and its relationship to economics. Upton Sinclair analyzes religious organizations as economic entities that are concerned not so much with spirituality as with profit. The author reveals the secret mechanisms used by the church and other religious institutions for material benefits. This book is an invitation to think about how religion affects the economy and society as a whole, and is a challenge to standard ideas about religiosity.
