““The habit of thinking about progress as "development" has meant that many aspects of the environment were simply neglected. With the stereotype of "progress" before their eyes, Americans have in the mass seen little that did not accord with that progress. They saw the expansion of cities, but not the accretion of slums; they cheered the census statistics, but refused to consider overcrowding; they pointed with pride to their growth, bu would not see the drift from the land, or the unassimilated immigration. They expanded industry furiously at reckless cost to their natural resources; they built up gigantic corporations without arranging for industrial relations. They grew to be one of the most powerful nations on earth without preparing their institutions or their minds for the ending of their isolation... There comes a time, therefore, when the blind spots come from the edge of vision into the center. Then unless there are critics who have the courage to sound an alarm, and leaders capable of understanding the change, and a people tolerant by habit, the stereotype, instead of economizing effort, and focussing energy as it did in 1917 and 1918, may frustrate effort and waste men's energy by blinding them, as it did for those people who cried for a Carthaginian peace in 1919 and deplored the Treaty of Versailles in 1921.””
