Final answer:
Henry Ford's assembly line is most known for significantly increased production and efficiency in manufacturing, leading to the production of goods at unprecedented rates.
Step-by-step explanation:
The introduction of Henry Ford's assembly line is primarily attributed to increased production in manufacturing. The assembly line revolutionized the automotive industry by increasing efficiency, which allowed the production of more goods in less time. Ford's assembly line created jobs that required minimal training and were repetitive in nature, but to compensate for the mundanity and high turnover, Ford doubled wages to five dollars a day and shortened the workday. This significant wage increase made Ford's factory jobs highly desirable, particularly among African Americans and migrants who moved to northern cities like Detroit for these opportunities, although it did not necessarily reduce migrant workers, reduce workplace accidents, or lead to a shorter overall workweek.
