Comic book is good, one of the better takes on alternative Superman's
But it does fall into the category of the USSR as misguided, with things only getting better after Stalin dies and Superman taking over
What does set it apart is the United States is portrayed as psychotically determined to bring down the USSR as humanly possible, even launching a nuke to try and kill Superman when he's fighting Bizarro in London
They and by extension Lex Luthor (since he ends up de facto dictator of the USA) eventually end up doing central planning and a nationalized economy anyway to try and keep up with the USSR
So the comic basically ends with everyone doing a Communism anyway
