By 1935, military expenditures accounted for 73 percent of the government's purchases of goods and services.[262] On 18 October 1936, Hitler named Göring as Plenipotentiary of the Four Year Plan, intended to speed up rearmament.[263] In addition to calling for the rapid construction of steel mills, synthetic rubber plants, and other factories, Göring instituted wage and price controls and restricted the issuance of stock dividends.[246] Large expenditures were made on rearmament in spite of growing deficits.[264] Plans unveiled in late 1938 for massive increases to the navy and air force were impossible to fulfil, as Germany lacked the finances and material resources to build the planned units, as well as the necessary fuel required to keep them running.[265] With the introduction of compulsory military service in 1935, the Reichswehr, which had been limited to 100,000 by the terms of the Versailles Treaty, expanded to 750,000 on active service at the start of World War II, with a million more in the reserve.[266] By January 1939, unemployment was down to 301,800 and it dropped to only 77,500 by September.[267]
