This review deals with new book of journalist and writer Andrei Ostalski «The Saviour of Capitalism. John Maynard Keynes and His Cross» published by Palmira publishing house. The book is intended primarily for the mass reader. The author does not compete with the dozens of studies on great economist written by professionals and designed for professionals. He tries in simple words and a fun way to provide the reader without economic background with the essence of Keynesian theory, with its critics and antagonists, as well as with the place that theoretical heritage of John Maynard Keynes takes in the contemporary battle of ideas. The reviewer believe that A. Ostalski successfully coped with the task and his book certainly will find its reader.
