The ever prolific Daniel Larison very deftly uncovers what is meant by the notion that we are a “nation of immigrants” in this entry. He writes:

The phrase is distinctly odd, since no nation today can correctly claim to be such a thing, as every people has been settled in more or less the same country for ages. There are nations that have had a history of periodic large-scale immigration, and this is usually what is meant by the deceptive phrase “nation of immigrants,” though it has long been the case for most of the history of this country the immigrants were not constituting the nation but instead joined themselves, more or less, to the people that was already here. If we spoke of a “nation of immigrants,” we might as well also speak of a “tradition of innovations” or a “constitution of amendments.”

But the reason why it is ingenious is that it forcibly identifies everyone in the debate–or at least everyone who concedes the use of the phrase–with the current immigrants. If we are a nation of immigrants, this means that we are all immigrants, which ultimately means that we have no more right to this place than the new immigrants do, which is a manifest lie. We do have more right to it, and will have at least until such time as we have been driven off the land, and perhaps our better claim will not cease even then.

Most peoples throughout history have created myths of heroic ancestors who first settled in a land and gave their name to it; most peoples will construct elaborate mythologies to establish their timeless claims to a piece of land. With this preposterous rhetoric of being a “nation of immigrants” (who is responsible for this travesty of language?), Americans are among the few nations in the world who pride themselves on not being from the land that they live in and making no attempt to pretend otherwise.

In other words, for us to be a nation of immigrants is just another way of saying we’re not a nation at all, a “nation” of foreigners. I think one goal in earlier descriptions of our nation as a “nation of immigrants was to make newcomers feel welcome as they struggled to conform to American mores. So what if you have an accent, we’re a nation of immigrants, just keep trying. A generous welcome wagon coupled with a firm commitment to assimilation generally prevented earlier waves immigrants from becoming an alienated, hostile, unhappy, and unassimilated mass. But today the phrase is employed to prevent native-born Americans from having the confidence to encourage any assimilation whatsoever.
