Roger Waters had a very negative view of mankind in the Seventies. On Floyd's 1977 LP Animals he divided humanity into three categories: pigs, sheep and dogs. The pigs are the corrupt politicians. Dogs are the aggressive, uncaring capitalists. The sheep are the masses that question nothing, going through life in a state of pure ignorance. Put another way, he had disdain for absolutely everybody. He also had little interest in recording songs like "Wish You Were Here" that would work on the radio. Instead, there's really just three songs on the album, though "Pigs on the Wing" is divided into three sections. The LP turned off some casual Floyd fans who loved songs like "Money" and "Have a Cigar," but the true believers were enthralled by the complex, epic songs. They supported the album with a huge stadium tour that only served to make Waters hate the world even more, though it did inspire him to start writing The Wall.
