[...] When Brecht, to take an example, devised a kind of childish shorthand to try and crystallize out the essence of Fascism in terms of a sort of gangsterism, he made his 'resistible' dictator, Arturo Ui, the head of an imaginary and apocryphal Cauliflower Trust, instead of the most powerful economic organizations. This unrealistic device proved to be a mixed blessing. By thinking of Fascism as an enterprise belonging to a band of criminals who have no real place in the social system and who can therefore be 'resisted' at will, you strip it of its horror and diminish its social significance. This invalidates the caricature and makes it seem idiotic even in its own terms: the despotic rise of the minor criminal loses its plausibility in the course of the play itself. Satire which fails to stay on the level of its subject lacks spice.
this begets the question of where the balance is you're trying to write dystopian fiction that still inspires. how powerful do you make the bad guy? how hopeless does the situation have to be? you want to create a scene that is horrifying enough to simulate reality but surmountable enough that the viewer leaves thinking, "I should fight back, too"
