A slave in a cell of our own choosing, one which is warm and comfortable, but nonetheless is still a cell. They get you from birth, fill your head with ideas that you need to be coddled and be a part of a team, they lead you to believe that individuality is bad and that conformity is good . Get you to believe that your country is an exception to all the others that war, and fight, and lie, and steal.
Slaves do not own their labor. Slavemasters found that slaves who felt free by having to manage their own wages to purchase that which the slavemaster used to provide, created more docile slaves. Now the slaves makes public speeches about their freedom, all the while giving a third of the fruits of their own labor to this unseen Master. Master doesn't use whips and chains, just debt and court systems and ultimately violence to enforce its "freedom" it has privileged you with.
