How did the economic depression help the Nazis?

The Wall Street Crash in October 1929 led to a world economic depression. Germany felt the impact of the Wall Street Crash earlier than many other European countries because so much US money had been pumped into the German economy since 1925 in the form of short-term loans. These loans were rapidly called in by American banks, resulting in a sudden fall in industrial output. Factories were forced to close or reduce their workforce. The result was increasing unemployment which soon brought millions of families to the brink of poverty and despair. Some historians believe that without the world depression the Weimar Republic would have survived and Hitler would not have gained power.
