Well, the lyrics are poorly written in a poetic or grammatical sense, aside from evaluating their content. For example, words that would be grammatically useful in intelligent speech are left out. A skilled poet can avoid doing that.
Anyway, part of my judgment on the nature of the clip was based on the fact that I knew it came from the special features of the DVD of The Corporation, which my economic professor had us watch. That DVD is, literally, the most offensive trash I've ever seen in my life. It's a giant polemic against capitalism and corporations that doesn't contain a single valid argument and rests almost entirely on feelings the "documentarians" evoke through satire, plain making fun of people, and so forth. This kind of piece is typical of their work.
In context of the film, it is purely offensive in that it is both anti-freedom and expects you to adhere to its claims by abandoning your mind. Out of the context of the film, it could go either way, but it's just of very poor artistic quality.
