Yes, regardless of if they win or lose, capitalism is maintained. Winning elections was never the point. That’s why they will never court left wing voters, even if they know full well trying to swing the mythical “moderate” republican will never work.
James workshop is also very bad at scale in their own universe though. You’ll have 100 year full scale wars over entire systems and the lore will say some shit like “3 million casualties of IG over the course of the war”; like that’s probably not even in the top 10 casualties list of imperial Chinese rebellions.
Worse is their space marine treatment, where apparently a million known space marines is enough to serve as shock troops over the entirety of their holdings in the galaxy.
Rule of cool and all, but every time I see a 40k novel mention numbers I have to add two zeros to the end for it to actually make sense given the quadrillions of imperials and the other quadrillions of their enemies.
