Through the entire Dark Knight saga, the day is never saved by hope, inspiration, or star-and-rainbow wipes. It's always science and/or cold, hard cash that comes through in the end. In Batman Begins, Lucius Fox, not a prancing unicorn, makes an antidote for Scarecrow's fear toxin. And if it wasn't for WayneTech's Tumbler, Gordon would never have been able to blow up the train tracks that the League of Shadows was using to distribute the toxin around the city. In the second movie, Batman finds the Joker using magic cell phone technology instead of magic hug technology.
Focusing on his job instead of listening to millions of people doing it is why he's Batman and we're not.
Simply put, if Batman was anyone but Bruce Wayne, millionaire psychopath, then he never would have been able to save the city. But no, it's the symbol that's important, not the private stealth battle planes or armored super suits -- any schmo could have those. What really saves the day is a bat symbol on a wall.
