Critique my soft sci-fi setting

I am worldbuilding a soft sci-fi setting called The Arm. The setting revolves around an interstellar humanity which is divided into many factions of a mostly ideological nature. Most of humanity lives within a socialist state, but the present day of the setting also contains a corporatocracy, an independent republic of heavy-worlders, a theocracy, and nomadic fleets of communal spacefarers.
