Absolutely not. Why would the elite consider him an enemy and viciously attack him if he was part of them?

He's mostly promoting many of the false narratives promoted by the Elite such as space, politics being real, transhumanism etc.. I understand Elon is their Top Boy, still think he is quite good though.

maybe even the elite have "black sheep" and unreasonable siblings who go and spend more than their fair share and the more responsible ones are tired of seeing all that

Maybe they do, I noticed Elon gets pretty nervous at times when he is telling his lies.
