Roger Waters - Pigs (Three Different Ones) (Live)

In the album's three parts, "Dogs", "Pigs", "Sheep", pigs represent the people whom Roger Waters considers to be at the top of society, the ones with wealth and power; they manipulate the rest of society and encourage them to be viciously competitive and cutthroat, so they can remain powerful. Waters suggests that the pigs manipulate the dogs in the lines "Gotta admit, that I'm a little bit confused/Sometimes it seems to me, as if I'm just being used" in the song "Dogs".
