Final answer:
The manufacturing of products in the United States has experienced both growth and decline over time and is influenced by economic factors such as globalization, labor costs, and resource availability.
Step-by-step explanation:
The manufacturing of products in the United States has experienced both growth and decline over time. In the early 20th century and during World War II, the United States was a major producer of goods, even out-producing other nations. However, since the 1970s, the percentage of goods and services produced by the United States has declined, with many manufacturing jobs being lost to countries with lower labor costs.
Factors such as globalization and the availability of resources play a role in why many products are now manufactured outside of the US. Although manufacturing still contributes significantly to the US economy and provides jobs, the percentage of the workforce involved in manufacturing has decreased over the years.
Overall, the manufacturing sector in the United States has undergone changes and is influenced by economic factors such as globalization, labor costs, and resource availability.
