I assume this is referring to the Great Depression.
To summarize, spending dropped dramatically, unemployment skyrocketed, the amount of people looking for work paved the way for reform and for people to work together, almost all banks closed, trading was near non existent at the time, people were homeless because they couldn’t afford their mortgage, farmers were forced to lower all of their crop prices due to the surplus they grew in preparation for the war, and a majority of children quit their current education in order to assist their parents working.
