Big Brother Concept

I believe the Big Brother concept can happen in real life because the government has so much power it would be hard to go against them. One way it's happening today is the yellow cab taxis having a Gps installed in their car. They can see everything they do. The negative effect to this is that they are invading they're privacy. The positive effect to this is they can check if they're goofing off. They may be wasting gas by using the cab for their own purposes, or doing illegal stuff like selling drugs.
