By 1938 (in five years) pulled Germany out of Great Depression. No other European or American leader was able to do that. Not even Franklin Roosevelt.
Did away with unemployment. Completely. In 1933, when Hitler came to power, there were six million unemployed in the country. By 1938, there was a shortage of workers (i.e. negative unemployment). Again, no other European or American leader was able to solve this problem
Achieved unheard of economic growth. Between 1933 and 1938 German GDP grew, on average, by remarkable 11% (!) a year.
Significantly increased real weekly earnings of German workers. From 1932 to 1938 gross real weekly earnings increased by 21%. After taking into account tax and insurance deductions and adjustments to the cost of living, the increase in real weekly earnings during this period was 14%.
Kept prices stable. Adolf Hitler was the only one national leader who managed to restore full employment and achieve impressive economic growth while keeping inflation at essentially zero (1.2% on average for consumer goods with some prices actually declining). Even after the outbreak of World War II, workers’ income continued to rise. By 1943 average hourly earnings of German workers had risen by 25 percent, and weekly earnings by 41 percent
Significantly increased industrial and agricultural output. Between 1932 and 1938 food consumption in Germany increased by 17%, clothing and textile sales increased by 27%, and sales of furniture and household goods went up by 50%. For the same time period, German motor vehicle production, , more than doubled in the five years of 1932 to 1937, while exports of cars increased eight-fold (!)
Radically increased the profitability of businesses. During the first four years of the National Socialist era, net profits of large corporations quadrupled
Radically improved economic situation in Austria after the Anschluss (actually, the spectacular economic transformation of Germany was the #1 reason why more than 90% of Austrians supported unification with Germany). Between June and December 1938 alone, the weekly income of Austria’s industrial workers rose by 9%. The unemployment rate in Austria dropped from 21.7% in 1937 to 3.2% in 1939. The Austrian GNP rose 12.8% in 1938, and an astonishing 13.3% in 1939 (more than in Germany proper).
And then he lost the war. Which all but completely destroyed the German economy
