Final answer:
Immigration by primarily low-skilled workers can have negative effects on American low-skilled workers, such as reduced wages and decreased employment opportunities.
Step-by-step explanation:
Immigration, particularly by low-skilled workers, can have disruptive effects on American low-skilled workers. Studies have shown that immigration weighted toward low-skill workers tends to reduce wages for domestic low-skill workers. For example, a study by Michael S. Clune found that for each 10% rise in the number of employed immigrants with no more than a high school diploma in the labor market, high school students reduced their annual number of hours worked by 3%. The presence of low-skilled immigrants can also lead to a shift to the right in the supply of unskilled labor, resulting in lower wages for jobs that low-skilled immigrants tend to take, such as restaurant and hotel work, lawn care, and janitorial work.
