How did Heinrich Himmler claim the evacuation of the Jews would help the German nation?

Himmler, a prominent Nazi, was part of the narrative in Germany that stated that the Jews could not be trusted.  His pseudo-scientific approach to understanding race was that the Jews were a less developed form of humanity and they must be removed in order for the Aryan race to fulfill their destiny.  Himmler also tied Communism to being Jewish since many of the leaders of the Russian Revolution were of Jewish ancestry.  In order to cleanse the state of disloyal people, Himmler authorized sending Jews to concentration camps in the name of racial purity.  He also made it illegal for Aryans to marry Jews.  In places the Nazis occupied, such as Austria and the western Soviet Union, he rounded up millions of Jews and sent them to camps so that the land could be occupied by loyal Aryans.  Himmler's distortion of science to serve his own ends was bought into by many Germans who believed that the best hope for the German nation resided in creating a race of pure Germans.
