Communism, religion, politics, labels, all of it is just there to divide the proletariat and make us collectively weaker, never able to truly unite and rise up and overthrow all of them across every government, every company, every scrap of dirt on this planet.

There are 8 billion of us. They need to control us all, all the time or else, god forbid, we just wake up one day, all of us, and say "No".
