Final answer:
Life-cycle service became less common because industrialization changed work patterns, moving from agricultural living and working within households to urban industrial employment. Improvements in medicine, sanitation, and nutrition also played significant roles in shifting employment structures during the 18th and 19th centuries.
Step-by-step explanation:
The life-cycle service faded during the 18th and 19th centuries primarily due to industrialization changing work patterns. The shift from agriculture to industrial work required a different labor structure, lowering the prevalence of services where individuals would live and work within the household of their employers for a period of their lives. This demographic shift was supported by other factors such as improved medicine and sanitation which lowered death rates and increased life expectancy.With the arrival of the Industrial Revolution, labor moved to factories which centralized work opportunities and created urbanization. Advances in science and technology, like the development of immunizations and improvements in public hygiene, advanced health standards. Sanitation systems prevented disease, while new medical treatments and behavior changes reduced mortality rates which in turn affected the traditional life-cycle service work arrangements.Furthermore, transportation improvements such as trains facilitated better distribution of food, contributing to better nutrition and health. This economic stability, as well as new opportunities, led to the decline of life-cycle service in favor of modern employment structures.
