It struck me today that two countervailing trends fighting against privacy are efficiency and security. Here are two quotes that summarize it quite nicely:
"My own hunch is that Big Brother, if he comes to the United States, will turn out to be not a greedy power-seeker but a relentless bureaucrat obsessed with efficiency"
Safety and Security
From Dostoevsky's The Brothers Karamazov, in the chapter about The Grand Inquisitor: "Make us your slaves, but feed us."
