Europe:
The economic depression impacted Europe because their economy was closely related to the United States. It affected them because their unemployment rate, people who don't have jobs, rose at 20%, and that is a lot of people that don't have jobs in Europe, which means that they can't get money to support themselves. Because of WWI, the economy was already in a lot of debt, and having to get more debt because of the great depression didn't help the economy at all.
United States:
The economic depression, the great depression, impacted the United States a lot. It impacted the United States a lot because it caused human suffering. The great depression made the citizens of the U.S depressed because of the stock market crash, which led to them losing all of their money. They had no hope in getting their money back, and they were saddened that they worked hard to get all of that money, then having it disappear.
The Great Depression affected BOTH Europe and The United States, specifically in the Industrial system.
