If we have structural problems (e.g. widespread corruption) then politicians alone won't fix it.

I can't say that I know whether Wikileaks is going to effective, or that it's going to cause any positive ourcomes, but it seems clear to me that if there is going to be positive action on corruption it's either going to happen as a result of a massive crisis (i.e. the system breaks down), or because a new force shines light on the corruption from outside, forcing politicians to act. Both paths carry a risk of things getting worse rather than better - although so does a slow decline resulting from inaction.

Personally, I'd hate to see any (more?) major breakdowns in society, and the idea of a slow decline is equally tragic. Perhaps wikileaks is doing it wrong, but the idea of a non-government actor exposing corruption - something the media has stopped doing - seems entirely healthy to me.
