Americanism means the virtues of courage, honor, justice, truth, sincerity, and hardihoodthe virtues that made America. The things that will destroy America are prosperity-at-any-price, peace-at-any-price, safety-first instead of duty-first, the love of soft living and the get-rich-quick theory of life.
Americans will listen, but they do not care to read. War and Peace must wait for the leisure of retirement, which never really comes: meanwhile it helps to furnish the living room. Blockbusting fiction is bought as furniture. Unread, it maintains its value. Read, it looks like money wasted. Cunningly, Americans know that books contain a person, and they want the person, not the book.
Another possible source of guidance for teenagers is television, but television's message has always been that the need for truth, wisdom and world peace pales by comparison with the need for a toothpaste that offers whiter teeth *and* fresher breath.
