How did mass production techniques such as the assembly line affect the us economy?

Mass production techniques, particularly the assembly line, revolutionized the U.S. economy by significantly increasing production efficiency and lowering costs. This allowed companies to produce goods at a much faster rate, making products more accessible to the general public and stimulating consumer demand. The rise of mass production also contributed to the growth of the manufacturing sector, creating jobs and fostering urbanization as workers flocked to factories. Overall, these techniques helped propel the U.S. into an era of economic expansion and consumerism in the early 20th century.
