"Common People" is a song by English alternative rock band “Pulp”, released in May 1995 as the lead single off their fifth studio album “Different Class”.
The song centers around gentrification and how an upper-class girl that studied sculpture at Saint Martin's College “wants to be like common people” .
“Rent a flat above a shop Cut your hair and get a job Smoke some fags and play some pool Pretend you never went to school” .
In this sentence, he generalizes the working class into people with no education that lives a street life, unbothered by the world around them, and only have themselves to think about.
A very primitive and simple lifestyle in my opinion, but with an ugly truth of loneliness and constant fear, because of a non-existent safety net that is not there to help them climb the social class hierarchy.
