Over time I have started to question the whole concept of Batman, how relatively recent iterations try to be serious but kinda just makes the concept of a billionaire ninja terrorizing common thugs seem less plausible and also somewhat fascist.
At the same time, the Nolan movies were sort of about addressing this (taking Batman Year One as its jumping-off point). For starters, they weren't about Batman beating up common street thugs or even crazy rogues, but systems of corruption every bit as powerful as him -- the mob and the police and politicians under their control. Batman Begins even addresses the economic inequality leading to this -- Bruce's dad invested in affordable public transportation (and used it himself) during a recession. We just don't see much of Bruce himself investing in that kind of stuff.
In The Dark Knight, Nolan-Bruce makes it clear he has no intention of being Batman long-term (the unlimited story structure is one of the reasons I don't read cape comics). His endgame was eventually turning himself in and leaving the hopes of Gotham to someone who could clean up the city legit. Dent straight-up draws the comparison to Roman dictators who took absolute power and then relinquished it.
The economic themes come to the forefront again in Dark Knight Rises, in which Catwoman is basically a lower-class version of Batman. The whole thing ends with Bruce abandoning his name and billions and running off with Selina.
All three Nolan movies are about Batman and the people around him grappling with the fact that they're sort of teetering on the edge of fascism. The villains of all three movies are anarchists.
