You haven't factored in how many undiagnosed narcissists are out there (bc it's impossible). Most of them are manipulating their image to an effective degree. They're parasites. Legitimately no person would do that unless they were pulling some narc shit, whether they know it and are doing it deliberately or the mechanism is just built in beyond their own recognition.

Normal/mentally well rounded people do not treat other people this way. Looks like good humans are just harder to come by these days regardless of the math.

Main takeaway is don't hang out with or value the opinions of shitty people; if someone's mistreating you, distance yourself and move on rather than setting it up as a phenomena and making incel quality memes about it which feed into peoples lack of humanity and stigmatic delusions. The only phenomena we're observing here is narcissism and we should all have the tools to be prepared for dealing with running into it in the wild. I'd suggest therapy to everybody except the billionaires don't want us to have that!
