I think this song is saying that corporations are manipulating human conciousness in order to obtain a monetary profit. I think the green belts thing means no new material can be built upon the already dumbed-down base of the human mind. And I completely agree, corporations are paying minimum wage to their employees, and saving that money to the fat cats at the top of the pile of money. But soon enough, that fat cat will be far too bloated to remain, and fall, sparking a landslide, and bringing the corporation with it. But as reliant on these corporations as we are, this would affect American lives. But we should not bury our roots so deeply into the soil of the corporations, but instead keep ourselves mobile and ready for change. Without that, we would tumble into the pit alongside the fat cats, lobbyists, and corrupt politicians.
