Final answer:
Foreign-born workers, including immigrants, make up a substantial part of the labor force in many countries. They contribute to the economy by filling jobs that native-born workers may not take on and performing essential tasks. However, they often face vulnerabilities and exploitation due to their immigrant status.
Step-by-step explanation:
Foreign-born workers compromise a significant portion of the labor force in many countries, including the United States. Immigrants, both documented and undocumented, contribute to the workforce and fill jobs that native-born workers may not be willing to do, such as harvesting crops, cleaning homes, and providing caregiving services. These foreign workers play an important role in the economy but often face challenges and exploitation due to their vulnerable status.
