George Orwell wrote the following paragraph in 1937 about English miners in his book The Road to Wigan Pier. Its sentiment, however, could apply to any number of workers in any number of industries in any country at any time in recent history:
It is so with all types of manual work; it keeps us alive, and we are oblivious of its existence. More than anyone else, perhaps, the miner can stand as the type of manual worker, not only because his work is so exaggeratedly awful, but also because it is so vitally necessary and yet to remote from our experience, so invisible, as it were, that we are capable of forgetting it as we forget the blood in our veins. In a way it is even humiliating to watch coal miners working. It raises in you 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 Literary Supplement 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.
