How are the Proles treated under Big Brother?

The proles of Oceania are generally completely disregarded and ignored by Big Brother and the Party itself. In terms of the authoritarian implications of the novel, it could be argued that the proles have it better than the Outer Party: they are spared the constant telescreen monitoring that the Outer Party must suffer, and they are not required to express support for the Party in the same way that members of the Party are.
The Party does not care to observe the proles because they know that they are too uneducated to ever unite. Machines create entertainment for them in the form of music and television, and they have little concern outside of their primary function, which is simply to work and create more proles.
