My comments: I cannot recommend this article to others. The title promises far more than this short article can deliver and Fusfeld speaks in generalities, makes sweeping generalizations. I think this important topic of big business-government relations requires a more detailed historical and empirical approach, much like Fusfeld used in his longer essay "The Rise and Repression of Radical Labor in the United States 1877-1918" (my post on that essay is here, which also lists most of Fusfeld's books), an essay which I do recommend and which had motivated me to read the article currently under discussion. Further, in the 40 years since this article was published there has been a significant evolution of the big business-government relationship which deserves our attention. However, I think the lack of detail in Fusfeld's article detracts from its suitability as starting point from which the student can begin to explore and understand the subsequent evolution. I suggest one instead consider the work of Thomas Ferguson.
