“So long as colonies and immigrant sections exist, with their inferior housing, sanitation, and care, Americanization will fail. It matters not at all that we satisfy our conscience by saying that immigrants prefer to live this way or that they lived this way in their own country. To say this is to forget that the crowded dwelling in Italy through which permeated the beauty and art, the religion, tradition, and association of the old country, is vastly different from the huts across the railroad track filled with strangers to whom the shop and saloon are the centers of gravity.”
