How would history have been different if Black Tuesday didn't occur at all?

Black Tuesday triggered a chain of catastrophic macroeconomic events in the US and Europe, which included mass bankruptcies and unemployment, and dramatic declines in production and money supply. Black Tuesday also triggered the Great Depression. It wouldn’t have taken 25 years to combat the stock market crash if it never happened and the Great Depression wouldn’t have been so bad because people wouldn’t have been so poor. Black Tuesday destroyed confidence in the economy. Banks went bankrupt and many were left unemployed in the US and in the UK.
