Answer:
During the Great Depression, which originated with the Crash of 1929, there was the most important economic crisis in the history of the United States. This crisis had a great impact on the rest of the most important economies in the world, such as Europe and Japan.
At the same time, the rise of Nazism to power was taking place in Germany. This caused thousands of Jews and members of other minorities to seek to leave Germany and Austria, looking for safe areas to relocate. But many of these areas where Jews sought to escape were mired in the crisis, so the arrival of these immigrant groups was not well accepted, since it added labor demand in places where work was scarce.
