As John Lennon said. There is a line about peasants later in the song too.

As soon as your born they make you feel small,
By giving you no time instead of it all,
Till the pain is so big you feel nothing at all,
A working class hero is something to be,
A working class hero is something to be.
They hurt you at home and they hit you at school,
They hate you if you're clever and they despise a fool,
Till you're so f'ing crazy you can't follow their rules,
A working class hero is something to be,
A working class hero is something to be.
