The Chateau digs up an early warning about the inevitable effects of immigration on America:
We find that our democratic theories and forms of government were fashioned by but one of the many races and peoples which have come within their practical operation, and that that race, the so-called Anglo-Saxon, developed them out of its own insular experience unhampered by inroads of alien stock. When once thus established in England and further developed in America we find that other races and peoples, accustomed to despotism and even savagery, and wholly unused to self-government, have been thrust into the delicate fabric. Like a practical people as we pride ourselves, we have begun actually to despotize our institutions in order to control these dissident elements, though still optimistically holding that we retain the original democracy.
Of course, economist John R. Commons was far from the first to observe the obvious:
“Another cause of revolution is difference of races which do not at once acquire a common spirit; for a state is not the growth of a day, any more than it grows out of a multitude brought together by accident. Hence the reception of strangers in colonies, either at the time of their foundation or afterwards, has generally produced revolution; for example, the Achaeans who joined the Troezenians in the foundation of Sybaris, becoming later the more numerous, expelled them; hence the curse fell upon Sybaris. At Thurii the Sybarites quarrelled with their fellow-colonists; thinking that the land belonged to them, they wanted too much of it and were driven out. At Byzantium the new colonists were detected in a conspiracy, and were expelled by force of arms; the people of Antissa, who had received the Chian exiles, fought with them, and drove them out; and the Zancleans, after having received the Samians, were driven by them out of their own city. The citizens of Apollonia on the Euxine, after the introduction of a fresh body of colonists, had a revolution; the Syracusans, after the expulsion of their tyrants, having admitted strangers and mercenaries to the rights of citizenship, quarrelled and came to blows; the people of Amphipolis, having received Chalcidian colonists, were nearly all expelled by them.”
And yes, that would be Aristotle, from the Politics
