This immigration (of Germans) stirred some nativist reactions. Not surprisingly, the greatest concern with immigration was in Pennsylvania which had, on the eve of the revolution, about one-third German in its population. Franklin wanted the Germans in western Pennsylvania to be better distributed in the nation and to mix more with the English. He worried that the new German immigrants would threaten the English language and English liberties, and so he insisted on Anglo-conformity as the model of immigration, demanding that the new immigrants conform to English ways.
Wright (1986:83) quotes the great philosopher and inventor as saying, "Why should the Palatine boors be suffered to swarm into our settlements and, by herding together, establish their language and manners to the exclusion of ours? Why should Pennsylvania, founded by the English, become a colony of aliens, who will shortly be so numerous as to Germanize us, instead of our Anglifying them?"
Franklin's ideas were standard for the day; in fact, standard for any day in the United States (see Gordon 1964:89-91). Worries about immigration were shared by many of the founding fathers (see Gordon 1964). George Washington did not want to encourage immigration and certainly did not want to see concentrated geographic settlement of any one group because he thought this would lead to the preservation of separate values. Even the liberal Thomas Jefferson worried about the impact on American liberty of the influx of immigrants from countries dominated by absolute monarchies.
