To me this song is about drugs and how they literally "take the farm" out from under your knees, how people who use drugs "chop down treetops" and "dig for diamonds at the bottom of the sea" where they will find no real meaning. This song, to me, is about the counterproductive nature of drugs and the people that use them, the way they're searching for something by using something that will never lead them to what they're looking for.
