"Among the number of applications..., cannot we find an American capable and worthy of the trust? ...Why should we take the bread out of the mouths of our own children and give it to strangers?"
John Adams - (Letter to Sec. State John Marshall, Aug. 14, 1800)
"The opinion advanced [by Jefferson,] is undoubtedly correct, that foreigners will generally be apt to bring with them attachments to the persons they have left behind; to the country of their nativity, and to its particular customs and manners. They will also entertain opinions on government congenial with those under which they have lived; or, if they should be led hither from a preference to ours, how extremely unlikely is it that they will bring with them that temperate love of liberty, [italics in original] so essential to real republicanism? There may, as to particular individuals, and at particular times, be occasional exceptions to these remarks, yet such is the general rule. The influx of foreigners must, therefore, tend to produce a heterogeneous compound; to complicate and confound public opinion; to introduce foreign propensities. In the composition of society, the harmony of the ingredients is all-important, and whatever tends to a discordant intermixture must have an injurious tendency."
Alexander Hamilton - ("Examinations of Jefferson's Message to Congress of December 7th, 1801," Jan. 12, 1802)
"Yet from such [absolute monarchies], we are to expect the greatest number of emigrants. They will bring with them the principles of the governments they leave, imbibed in their early youth; or if able to throw them off, it will be in exchange for an unbounded licentiousness, passing as is usual, from one extreme to another. It would be a miracle were they to stop precisely at the point of temperate liberty. Their principles with their language, they will transmit to their children. In proportion to their numbers, they will share with us in the legislation. They will infuse into it their spirit, warp and bias its direction, and render it a heterogeneous, incoherent, distracted mass."
Thomas Jefferson - ("Notes on Virginia," 1782)
""My opinion, with respect to emigration, is that except of useful mechanics and some particular descriptions of men or professions, there is no need of encouragement, while the policy or advantage of its taking place in a body...may be much questioned; for, by so doing, they retain the Language, habits, and principles (good or bad) which they bring with them."
George Washington - (Letter to John Adams, Nov. 15, 1794)
