stock market crash paper

I’m studying for my Economics class and need an explanation.

Watch the above video. Once you have done this create at least one page answering and explaining the following:

What were the major differences between the 1920s and the 1930s?
How did the end of WWI affect the U.S. economy?
Explain the relationship between Liberty Bonds, “Investing Culture”, Margin Buying, and the rapid appreciation of stock values in the 1920s?
Why did the major bankers meet at J.P Morgan’s office across the street from the NYSE? What did they subsequently do?
How did the “Liquidity Crisis” compound an even greater contraction in GDP after stock prices collapsed?
What means did Roosevelt implement to help stabilize stock markets immediately and long-term?
What effects did the Great Depression have internationally? Do you see any parallels today?
After you post your narrative, reply to at least two other students comments. Explain why you agree, or better yet, find others that take a different position and explain why you disagree.
make it a full page not including name or title.
