Technical material, in a sense, but fascinating reading, particularly for business men interested in the Thurman Arnold anti-trust investigations. For here an economist and analyst opens attack against Hitler's secret weapon, the ""spider web of cartels, patent exchanges, licensing arrangements"" which has enabled Germany to stifle American endeavor in strategic fields. The sensational tie between Standard Oil and Germany's industrial empire. T.G. Farbenindustrie, is first examined. Here one sees Germany extending tentacles of control over synthetic production, oil, gas, rubber, explosives. Then on to other industries, the partnership between General Electric and Kr for monopoly of tungsten, other alliances involving plexiglas, ammunition, optical instruments, in what is a damning exposure of big business. Controversial sales value.
