Book excerpt: Historically, the United States has been viewed by generations of immigrants as the land of opportunity, where through hard work one can prosper and make a better life. The American Dream is perhaps the United States’ most common export. For many Americans, though, questions remain about whether the American Dream can be achieved in the twenty-first century. Americans, faced with global competition and increased social complexity, wonder whether their dwindling natural resources, polarized national and local politics, and often unregulated capitalism can support the American Dream today. This book examines the ideas and experiences that have formed the American Dream, assesses its meaning for Americans, and evaluates its prospects for the future.
