Nothing More Dangerous

Ace of Spades HQ: Obama: Why, Just Imagine If a Worker Wanted to Extract Concessions from a Factory. And So He Stopped Working and Shut the Factory Down. Imagine Such a Thing. He'd be Fired!: "There's nothing more dangerous than the Egotistical Idiot whose personality dysfunctions effectively hide his incompetence from himself. Such a man will make mistake after mistake after mistake, and will never learn a damn thing from it, because his Ego will just keep telling him, "You're the best.""

He forgot narcissistic of course...
