Final answer:
The U.S. maintains a low unemployment rate because many service industry jobs that require physical presence can't be outsourced, and the impact of globalization is mitigated by trade with other high-wage economies and a varied immigrant labor force.
Step-by-step explanation:
America has been able to maintain a low unemployment rate despite losing many low-skill jobs to countries like India and China due to a complex set of factors. One pivotal element is that the U.S. has a high demand for service jobs that cannot be outsourced, such as lawn care services, moving and hauling services, or hotel maids. These types of jobs require a physical presence and are by nature local, ensuring a continued demand for low-skilled labor within the country.
In addition, globalization has not exclusively impacted low-skilled workers negatively, as the U.S. engages in a significant amount of intra-industry trade with other high-wage economies. These interactions tend to involve higher-skilled labor and more advanced products. Moreover, the U.S. economy has been bolstered by a diverse immigrant workforce that fills both higher-paid and low-wage jobs, which aids in maintaining the balance between various skill levels in the job market.
