This is from a great article on the immigration dynamic — It’s succinct, and hits on most of the key points. Here’s what Poor Richard was saying in 1753:
Measures of great Temper are necessary with the Germans … Those who come hither are generally of the most ignorant Stupid Sort of their own Nation … 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;
Few of their children in the Country learn English; they import many Books from Germany; and of the six printing houses in the Province, two are entirely German, two half German half English, and but two entirely English; They have one German News-paper, and one half German. Advertisements intended to be general are now printed in Dutch and English; the Signs in our Streets have inscriptions in both languages, and in some places only German …
In short unless the stream of their importation could be turned from this to other colonies … 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.
