"The Mammon Cult: An Essay in Economic Interpretation" is the work of the eminent American writer Upton Sinclair. In this book, the author deeply analyzes the problem of the influence of money and materialism on society. Sinclair reveals the mechanisms by which material values influence our perception of morality, culture, art, and politics. He urges readers to think about how property values can turn society into a consumer machine where only wealth is favored. This book is an invitation to think about true values and ways of liberation from the mammon cult, which distracts us from vital things.
