How did new industrial innovations such as assembly lines and mass production affect the American worker and the American consumer?

New industrial innovations like assembly lines and mass production significantly transformed the American workforce and consumer landscape. For workers, these innovations often led to repetitive tasks, which could result in job dissatisfaction and a decline in skilled labor, but they also created more jobs and increased wages in some sectors. For consumers, mass production lowered prices and made goods more accessible, fostering a culture of consumerism and enabling a wider range of products to be available. Ultimately, these changes contributed to the growth of the middle class and reshaped American society.
