What is one reason that more people didnt foresee the economic collapse of the 1930s?

One reason more people didn't foresee the economic collapse of the 1930s was the prevailing belief in the resilience of the U.S. economy, which had experienced significant growth during the 1920s. Many analysts and investors were overly optimistic, dismissing signs of economic instability, such as rising Stock Market speculation and income inequality. Additionally, the lack of effective regulatory frameworks and economic data made it difficult to predict the impending downturn. This combination of confidence and ignorance contributed to the widespread surprise when the Great Depression began.
