Final answer:
Immigration has positively impacted the US economy, healthcare, and indirectly, airline travel and world hunger. Immigrants contribute to increased production and fill labor gaps in various sectors, including healthcare. Additionally, their economic contributions can lead to indirect benefits in other areas.
Step-by-step explanation:
Immigration has benefited several aspects of life in the US, including the economy. Immigrants contribute to increased production and consumption, which can stimulate economic growth. Additionally, immigrants can fill labor gaps and perform jobs that domestic workers are unwilling to do, thus contributing to the overall economy.
However, the contributions of immigrants also extend to other areas, such as healthcare. Immigrants often work in healthcare occupations and contribute to the provision of healthcare services. They bolster the medical workforce and help address healthcare labor shortages.
While immigration does not directly impact airline travel or world hunger, it indirectly affects these areas. Immigrants' economic contributions can lead to increased demand for travel, potentially benefiting the airline industry. Similarly, their participation in the workforce can lead to higher tax revenue, which can be utilized to address social issues like world hunger.
