Big Brother and the party certainly take advantage of the Prole's ignorance and lack of knowledge. I believe the Proles are not under telescreen surveillance because the government knows they're harmless. By providing the Proles with Pornosec and Victory Gin, B.B. is "keeping them stupid". I think Orwell makes a good point here, and expresses how easily those who are uneducated can be controlled. What are your thoughts on the Proles, and how the government uses them?
