He saw the Jews as both, the blood-sucking capitalists and as the movers behind the evil communism which wanted to rob the Germans of their national identity. Having identified an enemy and demonized them, it was easier to garner -- in the name of remedying the situation -- the power he lusted for.
Fascism is the political structure which concentrates power into one branch of government. Hitler and Mussolini did this, and so did Lenin, Stalin, Mao, and Castro -- and all dictators of the "Left" and "Right."

The true living political spectrum is "command and control" on one side and anarchy on the other side.
Liberty and Freedom are just to one side of anarchy - definitely closer than most of us are comfortable with.
