Another issue is the impact of immigration on the labor market. Some critics argue that immigrants take jobs away from native workers, driving down wages and increasing unemployment. This can be especially problematic in industries that rely heavily on low-skilled labor, where immigrants may be willing to work for lower wages than their native counterparts. A study by the Economic Policy Institute found that immigration has a negative impact on the wages of low-skilled workers, particularly those without a high school diploma. In addition, there are concerns about the potential for immigration to undermine social cohesion and national security.
