" One day I walked with one of these middle-class gentlemen into Manchester. I spoke to him about the disgraceful unhealthy slums and drew his attention to the disgusting condition of that part of the town in which the factory workers lived. I declared that I had never seen so badly built a town in my life. He listened patiently and at the corner of the street at which we parted company, he remarked: “And yet there is a great deal of money made here. Good morning, Sir! "
