Nelson Aldrich Jr., the son, grandson and great-grandson of millionaires, did not set out to live his life as a sociological experiment. Yet though he was raised with many of the trappings of great wealth—the schools, the clubs and the summer homes—he was conspicuously lacking in cash. It was this singular deprivation that led to his discovery that it was less "the reality of unearned wealth" that guaranteed one's position in the world of "old money" than "imagination and pure training." In 1926, F. Scott Fitzgerald pronounced the rich "different from you and me." Now comes Aldrich to explain those differences in his new book, Old Money, the Mythology of America's Upper Class.
