Sci-fi all the way.
Battlestar Galactica (2003-2009) shows the fall of an empire (loosely, America) at the hands of their AI creations. I guess Rome or Britain could also sit in for America. This show aired while Bush the lesser was taking Afghanistan and Iraq apart piece by piece.
The Expanse (2015-2022) is the worthy heir to the throne of casting harsh light on the oligarchs and hegemons. Belters could be any people put upon by this corrupt system: migrant workers, Indigenous people, refugees, the unhoused, the descendants of the enslaved — anyone who was expected to bootstrap success.
Both are good shows. The Expanse is proving to be somewhat more resilient to the passage of time.
DS9 does so much right. It is certainly on point in its treatment of moral gray.
