Apparently, Lennon didn’t think that much of this 1971 song as the years passed. It was inspired by an interview the singer gave to Tariq Ali and Robin Blackburn of the Marxist newspaper, Red Mole. From this source, peaceful revolutions were inadequate to dismantle the existing capitalist system. It’s not clear if Lennon was writing from their perspective the way a fiction author may not necessarily believe in the thoughts and actions of their characters. However, the lyrics suggest support for a worker’s revolution of the kind that Karl Marx envisioned: to take to the streets and even violently usher in communism.
