Final answer:
American janitors earn more than janitors in India due to the higher productivity and difficulty of cleaning American office buildings, as well as the strength of the U.S. dollar compared to the Indian rupee.
Step-by-step explanation:
Labor demand-related reasons that American janitors earn more than janitors in India include the higher productivity of American office buildings and the difficulty of cleaning them. American office buildings may have more complex designs and larger spaces, requiring more labor and time to clean compared to Indian office buildings. Therefore, American janitors may earn higher wages to compensate for the additional labor and effort required in their job.
Additionally, the strength of the U.S. dollar compared to the Indian rupee can also contribute to higher wages for American janitors. When the U.S. dollar is stronger, it can increase the purchasing power of workers, allowing higher wages to be offered.
American janitors earn more than those in India because American office buildings are more productive, indicating a high demand for efficient cleaning services, which increases wages. Service jobs in the U.S. are also less affected by overseas competition.
Among the options provided, American office buildings are more productive is the labor demand-related reason that American janitors earn more than janitors in India. This touches on the concept of productivity and wages; as productivity in an American office building is usually higher, the demand for a clean and efficient work environment is also high, pushing up the wages for janitors. Furthermore, labor standards and working conditions tend to be more stringent in higher-income countries like the United States compared to low-income countries. This difference is also influenced by the fact that certain service jobs cannot be outsourced or replaced by imports from low-wage countries, which can maintain higher wages for these roles domestically.
