After WWI, there was a huge surge in technological developments in many areas of the U.S.. For the military, new "Tommy guns" were created. The first color motion picture appeared in 1922 for Americans to enjoy in their free time. For farmers, the mule drawn cotton stripper was invedted to make cotton harvesting easier. New technology was being invented across the country, and virtually all of America was giddy with the excitement of finishing the war and being so fortunate. What I'm wondering is, did those developments cause Americans to become overconfident with their situation? Did that lead to the Great Depression because they never expected the stock market to decline so suddenly? Did that element of surprise make it seem like the Depression hit even harder?
