Part A : For some reasons, the Nazis held the Jews responsible for the economic condition of Germany. In the first reason, it was established that they spread rumors that the Jews were stockpiling wealth and controlling the economy at the cost of the Germanite people. They said that the Jews engaged in usurious and profiteering financial schemes. By making scapegoats of the Jews, this reduced public discontent and anger from Nazi policies and helped refocus such to a target group deemed to be of the margins.
Part B: The nature of the communists posed an ideological as well as a political threat to Hitler's nationalist movement. According to the Nazis, communist ideology riven through with Marxist principles was seen as a rival ideology seated diametrically opposite to fascist and nationalist principles represented in their fronts. Hitler and the Nazis believed intensely in their supremacy of the Aryan race and the need to create a racially pure German state. Such views were obviously very much at cross purpose with the Communist aim towards internationalism, class war, and the complete overriding of all notions of private property.
Besides, politically speaking, communists were strong opposition contenders power-wise in Germany. They had a strong presence and support base especially in urban centres. The Nazis saw the communists as a hindrance to their rise to power and sought to eliminate them as a political threat. Hitler and the Nazi Party ruthlessly repressed and persecuted communists by arresting, imprisoning and being violent to them in an attempt at lessening and suppressing their opposition.
