Final answer:
Globalization contributes to economic growth and greater exports in the U.S., and can raise average wages via increased productivity, but its benefits are not spread evenly. Changes in the labor market depend on the country's industry structure and adjustment capacities, and globalization may affect job security differently across sectors.
Step-by-step explanation:
Globalization has had various impacts on the United States, including benefits like economic growth and greater exports. However, the effects on wages and job security are complex. While the average level of wages may increase due to enhanced productivity, this increase is not evenly distributed across all sectors. Globalization can lead to a shift in jobs towards industries where the U.S. has a competitive advantage, potentially increasing job opportunities and wages in those sectors. Conversely, industries without such advantages may see job losses. Workers in many developing countries endure labor standards and working conditions that would often be considered illegal in the U.S., such as wages below the U.S. minimum wage. This aspect can lead to criticisms regarding the ethics of globalization and its disparate effects on workers worldwide. Nonetheless, it is evident that labor market structure and the ability of industries to adjust play a critical role in mediating the impact of international trade on a country's workforce.
