Un Monde Sans Argent: Le Communisme was originally published in three parts, as three separate pamphlets, in France, between 1975-6. It was produced by Dominique Blanc, shortly after the dissolution of the Organisation des Jeunes Travailleurs révolutionnaires. The name Quatre Millions de Jeune Travailleurs was apparently 'adopted' from a 1971 PSU youth publication (Parti Socialiste Unifié - a French Socialist Party), presumably to satisfy French publishing laws, and texts continued to be published under this name through the 1970's including the widely distributed tract A Bas Le Proletariat/Vive Le Communisme. Whatever, though, the book speaks for itself. Just read it.
