There are unpredictable and complex problems that competence can't solve - see The Theory of Bounded Rationality.

So what happens when the "competent" can't solve what falls in their lap given constraints like resources/time/team etc?

They will either say we can't do it (someone else like Trump will put up his hand immediately and say but I can, I can do anything, Hilary is just a clown choose me). Or they will say we need to buy more time/resources/team etc.

The point here is - if they can't fend of the Opportunists and if they can't buy more time/resources etc by themselves but end up being reliant on some one that can easily be framed as incompetence and will be framed as such by Opportunists.

So you want to change the game, be honest about what "competent" people do when faced with unpredictability and complexity ie understand their limits. They generally exit the space. And others fill the space.
