I don't really know what the majority of the song is about. Maybe government lies, maybe something else. What I actually can interpret is the line "We had our chance to save the Garden/As it dies, our souls will harden". Looks a bit like a biblical reference to me (Not that I'm religious at all. Athiest actually) what with humanity having a chance to preserve the Garden of Eden in Genesis(?) and failing while subsequently having their souls "harden" to the world around them due to humanity's banishment from the Garden. Just my two bits.
