I thought it only proper to bring Chicken Little's rants into perspective with information from his own state's University:
http://www.colorado.edu/AmStudies/lewis/2010/migrate.htm#Since....many Americans at the time Crevecoeur wrote did not want to accept America as a nation of immigrants. John Jay wrote in The Federalist Papers (1787) that:
"Americans are one united people--a people descended from the same ancestors, speaking the same language, professing the same religion,..., and very similar in their manners and customs."

"So in the very earliest days of the English settlement,immigration began to be restricted, and Quakers and Baptists, Episcopalians and Catholics, were banished and proscribed from the Commonwealth on the grounds that American standards were apt to be impaired by their admission. From that day to this the older immigrants and their descendants have tried to keep this country for those already here and their kindred folk. They have looked upon themselves as a kind of aristocracy, their supposed superiority being proportioned to the length of time that they and their ancestors have lived upon this continent, and each successive generation of immigrants newly arrived has tended with curious repetition to adopt the same viewpoint, to believe that the succeeding immigrants were inferior to the former in religion, habits, education, or what not, and ought to be kept out."
A. Piatt Andrew (1914)

In the 1800s, White, Anglo-Saxon Protestant American elites tried to create a white, Anglo-Saxon Protestant (WASP) identity as the American identity. As a result, with the new wave of immigration to America between 1880 and 1920 of immigrants from Eastern and Southern Europe, many Americans feared that these new immigrants would never become Americans. One of the larger reasons for this fear is that the majority of these immigrants were Catholics or Jews, religions which many Americans saw as incompatible with American Protestant identity.
Between 1880 and 1920, Americans feared these new immigrants:
1. Strange customs and insistence on maintaining their cultures in crowded urban ghetto communities, such as the Polish ghetto, the Italian ghetto, the Russian ghetto, and the Jewish ghetto.
2. The massive influx of Catholics and Jews in crowded urban immigrant enclaves.
3. That these immigrants were responsible for social problems in the exploding, industrial cities, problems such as crime, poverty, insanity, and immorality.
4. Blamed immigrants for labor unrest and violence.
5. That these unassimilated immigrants were a threat to American culture and society. Feared that their ethnic enclaves threatened to undermine assimilation and the process of Americanization

In my opinion immigration policies cannot be completely ignored and, yes, there are some problems. But, Lamm is falling back on familiar old scare tactics that date all the way back to the American Revolution to mask his prejudices.
