George Orwell said this quote

“ Is a PLONGEUR'S work really necessary to civilization? We have a feeling that it must be 'honest' work, because it is hard and disagreeable, and we have made a sort of fetish of manual work. We see a man cutting down a tree, and we make sure that he is filling a social need, just because he uses his muscles; it does not occur to us that he may only be cutting down a beautiful tree to make room for a hideous statue. I believe it is the same with a PLONGEUR. He earns his bread in the sweat of his brow, but it does not follow that he is doing anything useful; he may be only supplying a luxury which, very often, is no luxury at all. ”
