Final answer:
Service industries tend to have more customer contact than manufacturing, which has seen a decline in jobs due to outsourcing and offshoring. Service jobs use fewer physical resources than manufacturing and rely on customer interaction, highlighting the impact of globalization on the workforce.
Step-by-step explanation:
Service industries generally entail a higher level of customer contact as compared to manufacturing which is where outsourcing and offshoring have historically been more prevalent. In service-oriented sectors such as plumbing, journalism, or marketing, there is some need for physical resources, but not to the extent required in heavy industry. Over time, service jobs have seen an increase whereas manufacturing jobs in the U.S. have experienced a decrease; this is due in part to the globalization of the workforce and the shifting of jobs overseas where educated, English-speaking populations, like in India, can offer customer service and other services at competitive rates. These global shifts emphasize the differences in operations between manufacturing and service execution, with the latter relying more heavily on direct customer interaction and less on complex chains of supply like those found in manufacturing sectors such as car production or large-scale factories.
