why does all American literature which we're asked to study in British classrooms revolve around the American Dream and its failings as an ethos except for ruthless capitalists... we've studied "Of Mice and Men", "The Great Gatsby", and "Death of a Salesman".

Is the best American literature about the fundamental flaws of the dreams, with all other American literature being toothless, meaningless shite with a lesser catharsis, or is British education encouraging us to be communists? If it's the former, can anyone recommend some literature praising America's culture and economic model, just so I can know it's out there?
