Original sentence: Also, the lyrics "Chop your breakfast on a mirror" are thought to be referring to cocaine abuse.Although the first is meaning is more likely, this somewhat fits with the power struggle theme of the album, as it can may be an addiction.The first is, along with other songs on the album such as Disposable Heroes, about a government or society overly controlling it's people.The lyrics "Master of puppets, pulling your strings" is thought to mean that a government or society is controling their people to the point where the citizens are "puppets" to their "master" and can do nothing to prevent being controlled by their "strings"
Edited sentence: The biggest hint at this is the lyric "Chop your breakfast on a mirror", referring to chopping cocaine.The first is, along with other songs on the album such as Disposable Heroes, about a government/society controlling it's people.The lyrics "Master of puppets, pulling your strings" is thought to mean that the government (or society) controls people to the point that they have no control.The other potential meaning is about cocaine abuse.This also fits in with theme of the rest of the album, since most of the songs are about a power struggle, much like an addiction
