To most people, this song is just pure hate toward the government (especially when you see the video clip), but I think there's more to it in the lyrics and even the music itself than that.
The unique thing in this song that to my knowledge almost none other has is the presence of a symphonic orchestra. I believe this instrumental choice has to represent wealth in general, this idea may seem to be abit strange at first, but is explained at some points in the lyrics.
One of the most important things to notice is the vocabulary that is being used to talk about money (spendings, receipts) and taxes (tiny shreds of his fiscal year), the use of "fiscal" year also means that the character inpersonated by the band here is in a relatively stable economical position.
This idea is also made by the fact that he has a second home and has the opportunity to open a restaurant which is quite an expensive spending (why he doesn't do it) even though it can be a good source of "profit" and provide work for several persons (but he doesn't want to give money to anyone anyway...)
Finally, the main character depicted by the lyrics is a stubborn and egoistic psychopath who would kill (someone else or himself regardless), or even conspire against the government just for some bits of money ! At the very end of the song, he talks about "engage[ing] the laserbeam" and I do not think someone who is struggling with taxes can afford such weapon, since first, it does not exist as weapon just yet and especially when the thing is depicted as a giant satellite in the video clip ...
As I see it, this song is more of a satyr of wealthy people who can't bear having to pay abit of taxes every year than a critic of the government that collects them.
