Schrag (Paradise Lost
) offers a scholarly history of the political movements that have sought to restrict immigration to the U.S. since its founding—from the 19th-century Know-Nothing Party through the years of American eugenics “research” that vastly influenced the Nazis in the years leading up to WWII. He points out how the same anti-immigration and anti-immigrant arguments have been recycled across generations: most notably the idea that certain groups—be they the Irish, Jews, Chinese, or Mexicans—were “inassimilable.” Though he doesn't provide any especially new insights, Schrag has assembled a fine history of nativist movements and the reasons why their rhetoric has been so seductive at particular points in history. The book would have been well-served had Schrag devoted more time to untangling the provocative idea he concludes with: that rather than “becoming white” and thus acceptable—the path trod by previous generations of European and Jewish immigrants—today's Latino and Asian immigrants may be shifting the paradigm and derailing the very mechanism that keeps the U.S. on a locked pattern of exclusion and race-based fearmongering against new immigrants.
