What Positive things Hitler did?

After the Treaty of Versailles( Which ended WWI) Germany had many problems. First and formost their economy was in VERY bad condition. They were desperate for someone. Hitler was that someone. He pulled them out of depression and in the 30s Germany lead the world in arts,organic foods, public school conditions,sports and enginering. While he was a anti-semetic murderer he technically improved Germany before WWII.
