The reference to average wealth probably used the wealth of the Jewish Rothschild family as the basis for its calculation. The Rothschild banking family is still believed to have had the largest private fortune in the world during the 19th century, as well as the largest fortune in modern world history. Although the Creditanstalt debts were assumed in part by the Austrian branch of the Rothschild family, its bankruptcy was later used by Hitler as an example of how the Jews were responsible for all the economic and social troubles of Germany and the world.
