At any rate, it should be pointed out that Diamond Joe Biden made that very point in his speech last Wednesday, among other points. It needed to be made; I'm amazed that no one made it, say, a full year ago.
This is not a small thing. Getting fired from a job is usually a traumatic deal. It can be up there with a death in the family, with potentially catastrophic consequences for the fired worker and their household. It encompasses the ability of someone to provide for their family. But Americans in particular are also conditioned to equate what they are with what they do, conflating career with identity.
Yet this is the underpinning logic for the Drumpfkins -- he's a great bidnessman, we've seen it on teevee. It's a baffling assumption, that someone whose main skill is pretending to fire people that don't actually work for them has superior insight on how to run the world's largest economy.
There are so many reasons that Drumpfski is unqualified for the office that he seeks. But the biggest one is not that he's a rude, thin-skinned, narcissistic man-baby -- it's that he's fucking incompetent.
