Immigration can revive declining civilizations only with selective and assimilationist policies

Evidence

It aimed not at disfranchising the immigrant but at ending the conditions under which his vote was sold. It succeeded brilliantly and in doing so completed the separation between nativism and municipal reform. — John Higham, Strangers in the Land, 691 (#complicates, via linked claim)
