Actually, Paul those were the very points Hoggart made in his distinguished study all those years ago. His concept of 'working class' was nothing like as simplistic as you seem to believe. Allowing for the 50+ years since its first publication, I think, if you were to revisit it, you would find it still had a fair bit of relevance to tell us about relationships between the different elements of our society. I don't think you would find it so dated as to have nothing to say any longer.
