Cover art for Ant lyrics by They Might Be Giants

This seems like a metaphor for the insidious way governments take Fascist control of a country with the citizens' consent.

See, the ant is the Fascist state. And slowly, it's gaining control of not only your body, but your mind. But you don't notice, because you're "asleep", you're not paying attention to the inner workings of your government, you're apathetic to it, one little ant can't create chaos, right? Except that while you were busy "sleeping" the ant has become the President. It calls the shots, and now it's calling your name.

Of course, a Fascist state follows, including men ransacking your house for whatever reason (Facist governments don't need a reason to terrorize their citizens; they're in complete control).

This could apply to the United States, actually. Except we're right between the second to last verse and the last verse. Just wait, Martial Law will follow soon enough.
