"The strongest argument for the un-materialistic character of American life is the fact that we tolerate conditions that are, from a materialistic point of view, intolerable. ... No nation with any sense of material well-being would endure the food we eat, the cramped apartments we live in, the noise, the traffic, the crowded subways and buses. American life, in large cities, at any rate, is a perpetual assault on the senses and the nerves."
