" The last two lifetimes have seen more scientific and technological achievement than the first 798 put together. The shift to a swiftly changing society has not greatly affected the surfaces of daily living. The New York of the 1980s resembles the New York of the 1930s more than the New York of the 1930s resembled the New York of the 1880s. But the shift has profoundly altered inner perceptions and expectations. It has placed traditional roles and institutions under severe and incomprehensible strain. It has cast off reference points and rituals that had stabilized and sanctified life for generations. It has left the experience of elders useless to the tribulations of the young. Children, knowing how different their own lives will be, no longer look to parents as models and authorities; rather, parents now learn from their children. "

― Arthur M. Schlesinger Jr. , The Cycles of American History
