In the 21 st century, Americans have experienced the impact of a globalized economy. It can be seen in relatively easy movement of people from one country to another. In the past, immigration was seen as a positive force for nation building. However, nowadays, immigration has become a problematic issue, especially when viewed from the perspective of limited resources and job places. Another aspect of immigration that needs to be discussed is discrimination in the workplace. Discrimination exists due to the stereotypes that employers and co-workers associate with a particular ethnic group. It is, therefore, important to appreciate the importance of immigrants in nation building, especially when it comes to the United States of America. The ability to see a big picture and the need to appreciate the contribution of immigrants to U.S. economy will reduce the incidences of discrimination in the workplace. There are two main issues when it comes to discrimination of immigrants in the workplace. First, there is the issue of competition and limited resources. The argument is that immigrants will compete with few jobs available to the unemployed. In other words, if the number of immigrants increases, there will be less jobs be available to the U.S. citizens. The source of discrimination was made even more problematic after the financial crisis that severely affected the job market in the United States. There was also the added challenge of outsourcing wherein American companies established businesses outside the country, especially in the countries with low wages. Therefore, many argued that it would not be wise to increase the number of immigrants because they would increase the competition in the jobs available in the market. As a consequence of this belief, the U.S. Federal government created laws that significantly reduced the number of immigrants allowed to enter the country. At the same time, these laws gave the power to search for, apprehend and deport illegal immigrants. There is the need to find out if these fears are based on real facts. Those who oppose immigration base their argument on the following statement that “a surge of low-skilled immigrants should increase the supply of such workers, driving down wages at the expense of working-class Americans” (Parker, p.1). It is easy to understand why many Americans are anxious when it comes to the presence of immigrants that can be viewed as competitors, when it comes to the job market. However, it is much more important to see the whole picture and realize that immigrant workers are indispensable to the U.S. economy. According to analysts, immigrant workers are important because “they do jobs most Americans wouldn’t take, for wages they wouldn’t want” (Quintanilla, p.1). A restaurant may not be able to operate without a chef, but it will also go out of business without a dishwasher. Furthermore, “lower-wage labor helps create more work for higher-skilled, higher-paid workers who are generally native born” (Isidore, p.1). The report from the U.S. Department of Labor gives another proof because it says that “at least half of the nearly 2 million crop workers in the United States are illegal aliens … the cheap labor they provide is crucial
