At the dawn of the 21st century the typical impression an American may have when the word “immigration” is mentioned can include much controversy. Immigration in the late 18th century was essentially a norm for the newfound American society. With Congress introducing bills like Arizona's SB 1070, it's quite clear that immigration is now one of the biggest American discussions in U.S. politics. Two interpretations of the topic at hand can be illustrated by examining Jacob Hornberger's essay “Keep the Borders Open” and Peter Brimlow's essay “A Nation of Immigrants.” Jacob Hornberger in his opinion clarifies that the main cause of the immigration problem is the establishment of laws that limit immigration; that he believed the founders of the United States would not tolerate restrictions on immigrants. In comparison, Peter Brimelow takes a definitive approach by addressing America's lack of homogeneity, which Brimelow believes is an essential characteristic of a nation. In both essays each author takes an indirect position on the topic of immigration. Hornberger implies that people should be allowed to do and live freely. Brimelow argues that America is not so much a nation, but a "political system" and that the only way for the United States to become a nation is to limit immigration and begin a process that would lead to unity and homogeneity . Jacob Hornberger Jacob Hornberger urges the reader to look at a moment in American history not only before immigration restrictions, but also before government interference in the lives of its citizens. By this the author means social services, welfare and other programs. He states that "[T]he fundamental principle underlying American society was that people should be free to live their lives in any way... in the middle of paper... in small groups of people who don't." understand each other. The differences could be for socioeconomic, gender or, above all, ethnic reasons. The only thing they attribute all these things to is contrasting differences. In West Hollywood a gay man of any ethnicity can live happily in a neighborhood of any socioeconomic status and with little to no discrimination, yet about six miles south of this neighborhood the same man could be beaten to a pulp simply for being if same. You could then take this same man and drive him 4,000 miles east to California and he could be discriminated against 300 miles in any direction - This is America - Brimelow understands this and executes this very effectively as he talks about a possible future nation. ..on one condition: close the borders and allow the trial to take place.
