Why Factors contributed to American consumer spending during the 1920s?

Several factors contributed to the increase in American consumer spending during the 1920s, often referred to as the "Roaring Twenties." The rise of mass production techniques made goods more affordable and accessible, while innovations in advertising and marketing created a culture of consumerism. Additionally, the widespread availability of credit allowed consumers to purchase items on installment plans, further boosting spending. Finally, the overall economic growth and rising wages during this period fostered a sense of prosperity and optimism among consumers.
