And he's a journalist who can go anywhere, hear and see anything, and then express himself to a broad public. In a way, Clark Kent could be more powerfull than Superman; what does he do with this power?
On a barely related subject, I read about Richard Dawkins expressing the fear that magical childrens fantasies could make children more likely to fall for religion. I don't know about that, I suspect that realising Narnia isn't at at the back of the wardrobe is probably a good first step on the way to questioning the other fantasies that one is presented with. But also, the regular dreams that we're presented with, namely money, fame and supercompetence, are so boring that we need something more. And something that can stimulate a belief in a better world, a more fun world, because we have to dream about it before we can make it. And I want a nice, fluffy world where no-one is hungry and every-one can be what they want to be and the walls glow electric blue or whatever.
