Excerpts from Books and Wikipedia
"What had caused the problem? Many Germans blamed the Treaty of Versailles and the need to pay reparations to the victors of World War I. The Nazis pointed to international Jewish financers, but the real culprits were successive German governments. They had taxed too little and printed too much money during the war, and they continued to do so after 1918."
