I think this song, as well as all others on this album, is based on the book 1984 by George Orwell. This whole song describes the government try to take over every aspect of the citizens lives. The symobl of the green belt is actually from the Green Belt Policy in the uk, which was an attempt to stop expansion. This totally makes sense now because the government is try to stop "expanding" our thoughts and mind. And in the book he talks about a totalitarian government. The significance of the red tape is the old tradition of putting read tape on important documents. But today it is considered to be an unnecessary document if it has red tape on it. Another symbol is the fat cat, which is considered to be a wealthy person who "buys his power" and corrupts the government. This is just what I have found. I had to evaluate this song for a project.
