I am aware that some contributors here do not believe that Gramsci's proposed methods were ever methodically implemented in the US, or that they continue to be propagated at almost twenty years from the fall of the regime responsible for their dissemination. I would not posit that every decision concerning advancement wihin the fields described is made by committee's whose sole determinant is "What would Antonio do?" but I do believe that affinity groups composed of his adherents (whether witting or unwitting) continue to conrol advancement within education and journalism or, wrt Hollywood, selection of "appropriate" product.
