The most accurate response to how industrialization improved life for many Americans is:
"Advances in technology led to more conveniences and a higher standard of living for a growing middle class."
While industrialization did lead to some positive changes in wage structures and labor rights over time, many workers, including women and children, often faced poor working conditions and long hours. However, the overall impact of technological advancements in transportation, communication, and manufacturing contributed significantly to the rise of a middle class and increased living standards.
