A history of the United States between 1938 and 1978 that explores the categories and convergences of class, race, and ethnicity. Measures how these three categories factored into World War II, the Cold War, and the Vietnam War. Begins with the veritable end of the large immigration period in America, moves through the political climate of the 1960s, and concludes with the impacts of American suburbanization, the blurring of categorical boundaries of class and ethnicity, and the strange persistence of class, ethnic, and racial differences amidst the continual shaping of what it means to be a citizen of the United States.
