People like Peter Thiel must be perpetually surrounded by yes-men to reach those levels of delusion. I assume its something that just naturally forms around people of such wealth and/or power. Like you must have close friends and family you trust to speak plainly to you or else your subordinates will naturally build a Potemkin village around you.
Remember how that TV anchor pointed to Thiel that he himself fitted all of his own descriptions of the Antichrist? It was clear no one had ever made that point to him before. Motherfucker was giving whole ass seminars on the topic and no one ever proposed that. He lives in a totally frictionless world. Its natural to become delusional under such conditions.
I don't want to be too sympathetic to them. They sinned to get into their position. But my point is its mentally unhealthy to be bourgeois.
