Answer :
Final answer:
The stock market crash in 1929, caused by a bubble fueled by margin trading and insider trading, ended the prosperity of the 1920s economy, exposing its vulnerabilities.
Explanation:
The marked turn away from the economy of the 1920s was primarily triggered by the stock market crash in 1929, known as Black Tuesday, that led to the Great Depression. This crash revealed underlying issues such as rising inequality, declining demand, rural collapse, and overextended investors.
During the 1920s, the stock market bubble fueled by excessive use of margin and insider trading inflated stock prices significantly beyond their actual value. This unsustainable growth led to a market collapse when credit tightened, causing the bubble to burst.
The crash of the stock market in 1929 marked the end of the Roaring Twenties, exposing the fragility of a booming economy built on credit and speculative investments. The economic repercussions of the crash plunged the nation into a severe economic crisis.
