As against the strain of social criticism that saw America as enfeebled by affluence and conformity, Allen wrote in praise of an economic system that had ushered in a new age of well being for the American people. Written at a time of unprecedented optimism and prosperity, The Big Change defines a transformative moment in American history and provides an implicit and illuminating perspective on what has taken place in the second half of the twentieth century.Allen's theme is the realization, in large measure, of the promise of democracy. In it he attempted to chart and explain the progressive evolution of American life over half a century. The Big Change was Allen's last and most ambitious book.

Best known as the author of Only Yesterday, Allen originated a model of what is sometimes called instant history, the reconstruction of past eras through vivid commentary on the news, fashions, customs, and artifacts that altered the pace and forms of American life.

Frederick Lewis Allen was one of the pioneers in social history.
