The major differences between the Great Depression and the Great Recession can be identified through economic, political, and social/cultural aspects.
Economic: The Great Depression was triggered by the stock market crash of 1929 and resulted in severe deflation, bank failures, and high unemployment rates. On the other hand, the Great Recession was caused by the subprime mortgage crisis and resulted in a housing market collapse, financial institution failures, and high job losses.
Political: During the Great Depression, President Franklin D. Roosevelt implemented the New Deal program to provide relief, recovery, and reform. In the Great Recession, President Barack Obama implemented the American Recovery and Reinvestment Act to stimulate the economy and prevent further downturn.
Social/Cultural: The Great Depression led to widespread poverty, homelessness, and a sense of despair among the American population. In the Great Recession, there was a significant increase in income inequality, with the wealthy recovering faster than the average population.
