How did mass production of production change consumer spending?

The mass production of goods significantly lowered production costs and increased the availability of products, making them more affordable for the average consumer. This shift led to a rise in consumer spending as people could purchase a wider variety of items, from household goods to clothing, often on credit. Additionally, the emphasis on advertising and marketing during this period encouraged consumers to spend more, as they were exposed to new products and lifestyles. Overall, mass production transformed consumer culture, fostering a more consumption-driven economy.
