Benjamin Franklin, one of the founding fathers of the United States of America, wrote this about German immigrants in 1753:
Those who come hither are generally of the most ignorant Stupid Sort of their own Nation… and as few of the English understand the German Language, and so cannot address them either from the Press or Pulpit, ’tis almost impossible to remove any prejudices they once entertain…Not being used to Liberty, they know not how to make a modest use of it… I remember when they modestly declined intermeddling in our Elections, but now they come in droves, and carry all before them, except in one or two Counties… In short unless the stream of their importation could be turned from this to other colonies, as you very judiciously propose, they will soon so out number us, that all the advantages we have will not in My Opinion be able to preserve our language, and even our Government will become precarious.
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, and will never adopt our Language or Customs, any more than they can acquire our Complexion.
The same xenophobia is expressed against immigrants today, 260 years later, alleging inability or unwillingness to learn the language, cultural incompatibility, different values, huge masses of people changing the face of the nation.
How did it turn out for the USA? Not too bad, I would say, despite or even because of the millions of German immigrants.
