Rebel alliance is kind of inherently communist in its basic definition

Hear me out. Yes, i know the alliance is to restore the (neoliberal) republic. However, while you are part of the alliance, you are not considered a mercenary. You don't earn anything for taking part of it. They just all seem to be able to eat for free in the cafeteria and I would even be surprised if there's a currency system at all within the Yavin base.

Credits are only used to hire outside mercenaries who are not part of the rebellion itself, or to buy minutia from outside contractors to be distributed among all of its different cells.

Im willing to bet this happens a lot in insurgent rebel grouos such as this IRL. I mean, those guys don't have time to work an actual job on top of this, do they? How are they living if not from shared common ownership of food, water, and any other necessities?
