It makes me think of someone fighting against the establishment, vs. for the establishment. Both are mere slaves to the system, to its laws and institutions and debts, just like most normal people are. But one is a slave fighting for freedom. The other is fighting for the freemen, or those with high enough wealth and power to be "free" from society's many constraints. The ones actually calling the shots in the long run.Does this quote make any sense to you "I am a slave, I fight for freedom, you are a slave, you fight for freemen, those are the doppelgangers."?
