The widest dispute between illegal immigration is from concerns with the United States economy. The economy has indubitably been affected by illegal immigration both positively and negatively. First of all, they provide cheap labor cutting costs for businesses. For domestic residents, immigrants generate a net economic growth. This is because immigrants produce new goods and services, increasing the labor supply. However, on account of them serving low-cost labor, the prices of these goods and services for consumers are decreased. A report from Gordon Hanson, University of California, San Diego Professor of Economics, determines that preventing illegal immigration will most likely impact the economy negatively, leading to a net drain. As mentioned above, the prices of some goods and services would increase. For example, in the article, “Retail Produce Prices Without Illegal Farmworkers”, Huffman and McCunn say, “The removal of illegal workers from the seasonal agricultural workforce would increase the summer-fall supermarket prices of fresh fruits and vegetables by about 6 percent in the short run and 3 percent in the intermediate term. During the winter-spring seasons, prices would rise more than 3 percent in the short term and less than 2 percent in the intermediate term. Imports would increase about 1 percent” (Retail Produce Prices Without Illegal Farmworkers). A majority of these illegal workers in the agricultural field are low-skilled and low-paying. Numerous Americans argue that immigrants take their jobs, yet many of these immigrants don't have a degree. In the cases where immigrants do have degrees, they often drift towards jobs that are technical and scientific, many times with little communication. Therefore, citizens without a college degree are the ones that suffer a negative impact from illegal immigration. This is exclusively valid to those in the fields of construction and agriculture. According to the Pew Research Center, in 2014, immigrants held 43% of agricultural jobs. Correspondingly, 27% of jobs were held by immigrants in construction.
