....I understood why those who had lived through war or economic disasters, and who had built for themselves a good life and a high standard of living, were rightly proud to be able to provide for their children those things which they themselves had not had.

Hence the materialistic and often greedy and selfish lifestyle of so many young people in the Western world, especially in the United States.
