[Brief part in Chapter 4 - Individualism and Work Ethic, Protestant America and Catholicism]
America was founded by British settlers who brought with them a distinct culture including the English languzge, Protestant values, individualism, religious commitment, and respect for law. The waves of immigrants that later came to the United States gradually accepted these values and assimilated into America's Anglo-Protestant culture. More recently, however, national identity has been redoded by the problems of assimilating massive numbers of primarily Hispanic immigrants, bilingualism, multiculturalism, the devaluation of citizenship, an the "denationalization" of American elites.
