Why is there no hope that the Proles will ever revolt and overthrow the Party?

The proles
are the commoners in the novel , and they are completely subjugated
underneath the rule of the Party. The rule of the party is pervasive, and this total control
keeps them from revolting. First of all, they have kept them impoverished to the point where
they can do nothing but take care of their daily needs. This near economic enslavement prevents
them from rising to the point where they can even think about the political situation and what
they could do about it. Beyond that, the Thought Police and other ministries are so deeply
ingrained into the society and have infiltrated even the proletariat citizens (as evidenced by
the surreptitious shop in which the main characters typically rendezvous) that it is impossible
to escape their control and monitoring. These two factors effectively prevent the proletariat
class from uprising.
