This Third Edition once more squarely addresses the topic which perhaps generates more passion, invective, and raucous debate than all others in American society today. Is multiculturalism a threat to us? Is there too much immigration? Are Americans no longer sufficiently 'American'? This book answers these questions by using history and sociology to shed light on socially constructed myths about the past, misunderstandings from the present, and anxieties about the future of American social and cultural diversity.
