If you actually listened to the lyrics you'd understand what it is about.
From my viewpoint, its about a person being born into the world, and from that very moment having everyone tell them what they should and shouldnt be/do/want. About how "the man" wants us to all do the same thing and become mindless robots, cogs that are part of a machine. And then goes into how being an individual and doing your own thing is seen as bad, and how by following what others do, you go and deny yourself and regret your life at the end.
