You forgot the YOB's superpower. Can't feel shame. He's actually quite skilled at shaming cowards into kowtowing, but no counterattacks are possible because the shame just rolls off him. Or maybe it's more like dark matter passing long time ago?
While I agree with your position more than your wife's, I also think "belief" doesn't matter to him. Memory of a goldfish and he "believes" whatever he just said and then "believes" the opposite in his next sentence.
But I found your post on the search for "evil". My basic position is that Amazon is evil and Bezos wants to the the king of evil. Largely due to the customer manipulation tactics. Scientific lying guided by the most profitable applied psychologists. On that side, I'm reading The Choice Factory by Richard Shotton for marketing scumbags seeking more sales. Is it a bestseller within Amazon? Converging with several other recent books, though the most potent is The Chaos Machine by Max Fisher, where the focus is on the psychology of fostering extremism and reprogramming people for more evil behaviors... Mostly focused on Facebook and YouTube, though Amazon gets a few mentions.
At a different level, I don't think it's exactly that we are becoming too stupid to survive (per The End is Always Near by 'influencer' Dan Carlin), but more of a compression problem that is making it more and more difficult to find and recognize true information. In short, language compresses reality, and written language (especially in books) compresses language and subverts the visual cortex for huge storage capacities. Unintended consequences, anyone? And now we humans are collapsing into a fog of cute AI-enhanced cat videos? (Though yesterday's example was actually a 'cute' exercise video from a physician, the better to walk farther...)
Oh yeah, I probably should clarify YOB. Yuge Orange Buffoon. I reject the YOB's own branding. It's clear the YOB doesn't "believe" in the existence of bad publicity.
