Your statement was partially incorrect.On 30 January 1933, Adolf Hitler was appointed Chancellor of Germany.
One could also state that: "From the time of Hitler’s appointment as Chancellor of Germany in 1933 until the start of WWII in 1939, Germany was not at war with any country or state, but at war within itself. The result of this internal war was the war known now as World War II."
Perhaps the prosperity of some portion of German citizens improved, but it was on the expense of much death and brutality to other German citizens.
In the end, the expense was even greater, as anyone with a rudimentary knowledge of WWII knows.
