The progressive responsibility of socially conscious and civic-minded billionaires, (an extremely endangered breed both in Gotham and our real world) had to be summed up by an ecoterrorist acting the part of a lovely socialite (Marion Cotillard); "You have to invest to restore balance to the world." Bruce has been lacking in his duties, and that evil that he and Commissioner Gordon buried isn't dead, but rising up once again.
Bane's movement is a false one, as he tells the people of Gotham that he is not a Conquerer but a Liberator, but in actuality he is neither. Bane is the Destroyer. Spinning a hopeful message in the wake of his havoc, telling the people to "take control" of Gotham, Bane uses his "truth" to get the citizenry to "tear down a corrupt city" and reclaim what is theirs from the rich oppressors who had peddled their myth of opportunism.
And it is not just any "ordinary citizen" who holds the detonator to their destruction, but equal parts rich girl and terrorist-anarchist. These masterminds did not just create a populist movement to fulfill their diabolical plot, but infiltrated powerful corporations with their subterfuge as well. For comparison, real-world anarchists, despite practicing just another political philosophy, are readily depicted by the media as murderous terrorists. Protestors, despite exercising their constitutional right to assemble, are either beaten or made into bridge bombers by the FBI. Even those who have read the anarchist or socialist literature pale in comparison to the bloodthirsty Bane army. But the fear has been writ large in the news: if a lone nut like the joker can inspire a depraved massacre in a theatre, what would an evil warlord and his army of mercenaries inspire?
Like the Batman, authoritarians do seem to create their own enemies.
What follows once the structures fail lacks even more subtlety; in the face of such wanton violence, the government will abandon you. The good cops will attempt to salvage the status quo, and the bad cops will either desert or work against the people. Idiotically and blindly following orders, in fact, could get orphans and priests killed. Only the Batman can save us.
As even Selena realizes too late, this is not what the 99% ever wanted. Their system has swung wildly from an authoritarian, decadent state to the bloody turf of a mad warlord. It is the Dark Knight who is the hero we need, but unlike any known billionaire, he is now humiliated and humbled, fearful, responsible, accountable, and thus strengthened, empowered, respectful and focused. "Hardened by pain... not from privilege."
It really should go without saying, by the way, that is not until Bruce Wayne loses all of his money, loses nearly everything, in fact, and is dropped into a pit to rebuild himself, that he is worthy of becoming a savior. And even though he still uses all those wonderful toys that only his previously privileged life could have afforded him, there can be no real-life analogue for his virtuosity. Nobody has done as much as the fictitious Wayne family for the good of society, building roads and trains and orphanages and hospitals. And no playboy industrialists don a mask and fight crime. And the Batman can't save the people with half-measures, by the movie's end, he must give us everything.
As super-fan of the Batman, Kevin Smith, points out:
"In our world it's not the case. The richer one gets, the less moral one seems to become. Not in all cases, but you hear about everything that just happened to our economy in the last few years... at the end of the day, Bruce Wayne/Batman [is] a moral example of a billionaire... Right then and there you should be able to divorce yourself from reality because no billionaire would waste their time helping others."
This establishes the film's central conceit as high fantasy. The Batman doesn't have what we'd normally call superpowers, and we've seen it's not simply the gadgets or money that keeps him going, but his rigid moral compass and drive to do good that makes him superhuman.
It isn't just allegorical. It's not just a cautionary tale. It's a mad thought experiment. Fiction. Fantasy. Though some of us do have trouble separating that.
For there is no Ayn Randian perfect citizen or engine of the economy that somehow magically makes everything better. There is no Nietzschean Übermench. In the face of the very real threats of depraved elites, deadly terrorist groups and savage gunmen, there are no real superheroes.
Batman will not save us.
