I can't recommend BANANA FISH enough, though the original manga is more explicitly Marxist with regards to its criticisms of the US government and its anti-communist actions in Europe and Asia throughout the Cold War. The main villains are the Corsican Mafia (and their creation by the CIA as part of Operation Gladio), and the CIA (with its imperialist involvement in Vietnam). The anime modernized it by changing it to the Iraq War rather than the Vietnam War, so not everything makes sense from a materialist point of view in that version, but it's still definitely worth a watch. Heavy trigger warnings for mentions of child abuse (not explicitly shown, but the show doesn't tiptoe around the fact that the CIA and FBI used and groomed vulnerable populations for their experiments), drug abuse, trafficking, brainwashing, basically everything the CIA was and still is up to.
