Jefferson on immigration
"Although as to other foreigners it is thought better to discourage their settling together in large masses, wherein, as in our German settlements, they preserve for a long time their own languages, habits, and principles of government, and that they should distribute themselves sparsely among the natives for quicker amalgamation, yet English emigrants are without this inconvenience. They differ from us little but in their principles of government, and most of those (merchants excepted) who come here, are sufficiently disposed to adopt ours." --Thomas Jefferson to George Flower, 1817.Source: Thomas Jefferson on Politics & Government
"[Is] rapid population [growth] by as great importations of foreigners as possible... founded in good policy?... 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. These principles, with their language, they will transmit to their children. In proportion to their number, they will share with us 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 Q.VIII, 1782.
