A depression can happen any time. Many economists disagree on what causes a depression but some think it is caused optimism or pessimism. When immigration or higher birth rates tend to grow, that could cause an expansion but when the population stops growing that is what causes a depression. Inventions like the automobile and the color television causes an expansion, but when everybody has one of these, people don't buy anymore and the company might go out of business which can lead to a depression. Depressions hurt thousands people, and a lot of them are worker's who lose their jobs.
Bank failures wipe out the savings of many people.
During depressions people feel angry and embarrassed because they have to live on charity. They also feel embarrassed because they can not support themselves. Depressions also cause marriage and births go down because people do not have money, homes, or jobs to support their children.
