How might the economy of the 1920 have a different without the advertising industry?

Without the advertising industry, the economy of the 1920s might have experienced slower consumer spending and less rapid industrial growth. Advertising played a crucial role in creating demand for new products and lifestyles, driving consumption and contributing to the economic boom of the decade. The absence of persuasive marketing could have led to a more conservative approach to spending, resulting in reduced innovation and less competition among businesses. Consequently, the overall economic expansion and the cultural shifts associated with the Roaring Twenties might have been significantly muted.
