Hitler wanted to avoid the economic problems faced after WW1.
He issued a series of war decrees in December 1939 which outlined vast programmes for all aspects of war production.
German military expenditure doubled between 1939 and 1941, however Britain trebled its expenditure in the same period.
Food rationing was introduced from the very start of the war, and by 1941, 55% of the workforce was involved in war-related projects, and 61% in 1944 - this did lead to less consumer goods.
