Pulp is a band from England, from a city called Sheffield. Most people coming from Sheffield belong to the working class, hence the song name Common People.
Most people know Pulp by their lead singer, Jarvis Cocker, when he made headlines by jumping onto the stage while Michael Jackson was performing. The song is from 1995
Another theme is, of course, common people. The song is about Cocker (The narrator of the song) and people like him who are from the lower class.
The lower class not only live in fear and hopelessness they also must deal with always feeling poor. This song exemplifies the wit that gives this class a voice, as well as the wild anger that drives them.
The lyrics mock those who glamorously portray poverty and believe that participating in "slumming" will make them a "common" person.
