Explanation:

The Bonus Army was a group of veterans of the First World War who marched to Washington DC in an effort to obtain their bonus payment. This march, and the reaction of the government, was an important event that occurred during the Great Depression.

After the First World War, the US Congress UU He voted in favor of giving a bonus to the veteran soldiers who fought in the war. They will be paid $ 1.25 for each day they provide services abroad and $ 1.00 for each day they serve in the United States. However, this money would not be paid until 1945. Since the First World War ended in 1918, this was a very long time to wait.

When the Great Depression began, many veterans were out of work. They wanted to get their bonus payment ahead of time to help pay for food and shelter while they were looking for work.

your answer would be just capitalism.
