The working class is unrepresentable, to the bourgeoisie.

The whole point of Warren Montag’s Marxist reading was to highlight the beast fable that Mary Shelley had created by portraying the protesting and work hardened masses as one giant bloodthirsty and demanding monster. To Shelley, it is unchecked scientific progress, and not capitalism, that created the wrathful beast known as the lower class and Montag rightly disagrees. He even reasons that, “the very logic of capitalism has produced the means of its own destruction: the industrial working class” (473). The monster at the end of the novel even rationalizes that the idea of rebelling against the bourgeoisie (Victor Frankenstein) was a mistake because he had spilled the blood of those close to him. According to Montag the bourgeoisie, seeing the monster as alien and irrational, would not be able to identify with it or sympathize. In fact, as Montag quotes Goldner, he claims that “the monster is a factitious totality assembled from (the parts of) a multitude of different individuals (Goldner)” (473).  They can only think and yearn for its destruction and in the novel’s final moments that dream is realized. Instead of bourgeoisie defeating the beast, it is the beast who does the deed. In addition to offing himself the creature, regretting leading Frankenstein to his death says “while I destroyed his hopes, I did not satisfy my own desires” (Shelly 197).

Basically, the novel Frankenstein is Shelly saying that all people who protest are indistinguishable from each other because they are monsters and we should just leave the poor alone :^( and ask nicely to be treated better :^(
