"In seven years, we'll have the highest percentage of Americans non-native born since the founding of the republic. And some people think, "Well, we've always had these numbers." But it's not so. This is very unusual. It's a radical change. And in fact, when the numbers reached about this high in 1924, the president and Congress changed the policy, and it slowed down immigration significantly. And we then assimilated through the 1965 and created really the solid middle class of America, with assimilated immigrants, and it was good for America."
