There are no "factions" in Disco Elysium, only people and their ideologies, historiographies, sociologies, and etc. The politics don't play out as if there is some extant opposition, people hold on to their ideologies as a coping mechanism for living in the wake of Communism's failure and the victory of Old World Power. The people of Revachol live at the intersection of every contradiction in the world system. You wake up from a self-destructive stupor in the middle of a class conflict for which there is no way to resolve as an individual actor. You can only minimize the damage. The best thing you can possibly do is live to serve others, not your self or an abstraction like nations, or the sclerotic vestiges of old powers.
What's accomplished are the consequences of your actions. How your life impacts others. Love and selflessness are what plant the seeds of a better world. The best people want a world that's good to everyone. Not a world that manages itself by being "good enough" at the expense of society's fringes. That's the point of Disco Elysium.
