The Jews were less than one percent of the population of Germany during the Weimar Republic. The Weimar Republic was the period from the end of World War I to the rise of National Socialism.
After World War I Germany was required to pay astronomical reparations to the Allies. This left Germany's economy in ruins with its currency rendered all but worthless. Adolf Hitler rebuilt the German economy by using a credit program rather than a gold-based currency.
Hitler began his national credit program by devising a plan of public works. Projects earmarked for funding included flood control, repair of public buildings and private residences, and construction of new buildings, roads, bridges, canals, and port facilities. The projected cost of the various programs was fixed at one billion units of the national currency. One billion non-inflationary bills of exchange, called Labor Treasury Certificates, were then issued against this cost. Millions of people were put to work on these projects, and the workers were paid with the Treasury Certificates. This government-issued money wasn't backed by gold, but it was backed by something of real value. It was essentially a receipt for labor and materials delivered to the government. Hitler said, "for every mark that was issued we required the equivalent of a mark's worth of work done or goods produced." The workers then spent the Certificates on other goods and services, creating more jobs for more people.
