Final answer:
Contemporary immigrant groups may be narrowing the income gap over time.
Step-by-step explanation:
In terms of income, contemporary immigrant groups may be narrowing the income gap over time. Recent immigration to the United States has led to a shift in the supply of unskilled labor, which has resulted in lower wages for jobs like restaurant and hotel work, lawn care, and janitorial work. While low-skilled U.S. workers who must compete with low-skilled immigrants for jobs may suffer from immigration, the middle- and upper-income households that purchase the services of these unskilled workers benefit from these lower wages.
