Without a doubt
Back in my rock & roll days I spent more than a few late nights in gin mills and honky-tonks, downing beers with world experts on economic policy, foreign relations, and national security issues. Well, they sounded like world experts.
I was always impressed with the certainty and assurance with which these self-ordained authorities offered solutions to every societal problem imaginable. (I also wondered how these barroom denizens found the time to do the exhaustive research upon which their confident pronouncements had to be based.)
Likewise, in the public square today I am struck by the fact that candidates (at least one, anyway) for the highest office in the land can expatiate with total certainty on solutions to decades-old issues—without any apparent education in them.
