Even if the wall supporters do not believe that a wall is a social barrier, they should realize that a wall would not be effective at stopping illegal immigration. Supporters of Trump’s wall, however, promise that a wall would limit illegal immigration. Actually, the government has tested fencing on a farmer’s land that is on the border; the farmer stated that the fence that is most similar to the wall is 90 percent effective (Richey, “Inside Trumps Wall” par. 26). Most wall supporters preach that an illegal individual can not cut through a wall like one can cut through a fence. Ultimately, these supporters do not understand that the southern border is not the only way to get into America. As a matter of fact, the United States Government does not know how many illegal aliens are in the country because of overstayed visas. For example, when a congressman asked a member of the Obama administration the number of illegals that were in America citing overstayed visas, the congressman answered, “we don't know” (qtd. in Nixon, “U.S. Uncertain of How Many Overstayed Visas” par. 2). That response from a member from the Obama administration is a simple, non-satisfying answer. His answer highlights the fact that the government does not know the amount of illegals that are actually in America. Also, a statistic stated in an article written by Ron Nixon entitled “U.S. Uncertain of How Many Overstayed Visas” mentions that “the Immigration and Naturalization Service, puts the number of people who overstay their visas at 40 percent -- which now would mean about 4.4 million of the estimated 11 million undocumented residents in the United States” (par 9). In other words, the statistic put out by the Immigration and Naturalization Service states that almost half of the illegal aliens in the United states are those of which have overstayed their visas-- not crossed the border illegally. With visas out of the question, the wall would not lower the amount of illegals in America because the immigrants are not pouring into the country the way that they used to. On the contrary, wall supporters insist that a wall will protect the economy because they think of outsiders as threats to their pocketbooks (Cook par. 6). However, these supporters do not know the real facts. First, Douglas Massey, a professor of sociology at Princeton University, explains that “the border is already as secure as you are ever going to get it” (qtd. in Richey, “Inside Trumps Wall” par 43).The professor insisted that, in 2008, the large quantity of immigrants traveling over the border diminished quickly (qtd in Richey, “Inside Trumps Wall” par 44). In addition, the amount of immigrants that have been caught at the border is at its lowest point since 1972; the professor explains that this is because the birthrate in the ‘60s was around six children per family and there were a lot of illegals entering the country because Mexico did not have enough jobs for the amount of people they were producing (qtd in Richey, “Inside Trumps Wall” par. 45). This makes sense-- if every household had six children in America, then the United States would also run out of room. Today, however, the birthrate is only around 2.2 children per household, and the amount of jobs in Mexico are significantly higher than the amount of jobs in the 60s(Richey, “Inside Trumps Wall” par 43). As a result, the amount of Mexican immigrants who have a need to come into America today is considerably smaller than the number of immigrants that needed to immigrate to America in the past. This means there is no reason to build a wall now because the illegal immigrants who are in the United states have been in the country for years, and there is not a reason to build a wall because there is not a significant number of illegals coming across the border today. Even if the amount of illegal immigrants coming into America were not diminishing, there would still be no way to stop illegal immigration due to supply and demand. Many Americans worry that illegal immigrants threaten their job security and economy (“Undocumented Immigrants” par. 1). However, as long as America needs illegal immigrants to work in places that citizens do not, there will be a need for illegal immigrants. Mexican drug cartels actually go into Mexican neighborhoods to offer to take people across the border so that they can find work(Eichenwald par 9). Nonetheless, the individual being smuggled always has to return the favor in some way. Moreover, this does not come without a price to the one being smuggled. According to a border agent, Coyotajes, the gang affiliated with getting people across the border and even creating false paperwork, earned as much as 6 billion each year(Eichenwald par 10). As this proves, human smuggling across the border is a humongous industry and even if a wall is established the smugglers will always find other ways to enter America.
