"In a way it is even humiliating to watch coal-miners working. It raises you in a momentary doubt about your own status as an 'intellectual' and a superior person generally. For it is brought home to you, at least while you are watching, that it is only because miners sweat their guts out that superior persons can remain superior. You and I and the editor of the Times Lit. Supp., and the Nancy poets and the Archbishop of Canterbury and Comrade X, author of Marxism for Infants - all of us really owe the comparative decency of our lives to poor drudges underground, blackened to the eyes, with their throats full of coal dust, driving their shovels forward with arms and belly muscles of steel."
George Orwell, The Road to Wigan Pier
