symbolism- what does the dream of max fighting with the futhrer symbolize??

In Max's fantasies of fighting Hitler, he can take hours of punches one-on-one, then beat the Fuhrer in just seven blows. Yet Hitler then announces that Max is a threat to the German people and commands them to defeat him. Max's cartoon depicting Hitler as a conductor symbolizes Hitler's total control over the German people, who obey his commands no matter how violent or illogical they are. Max sees himself as up against an entire brainwashed nation, yet he maintains his fortitude as he exercises.
