Just saw Dark Knight Rises. Cool stuff! I thought of this piece when I watched it. Yeah, Bruce Wayne is definitely more of a feudal lord than a Bain-style capitalist who spends all day watching financial numbers go up and down and jumping in to make quickie deals. Bruce is definitely more of a baron whose estate largely runs itself so that he is largely free to concentrate on other things.
Is this movie a story of a lone hero who singlehandedly saves everybody? Ehh, not really. As I noted with Thor, whose “posse” consists of the Warriors Three, Thor isn't really a Superman-style lone hero as much as he's the head of a small super-hero team who occasionally has to go running off on his own. Batman definitely has a posse here and clearly has to lean on folks to carry on in his absence when he's taken out of action.
