Tim Dillon said summarized it pretty well - can't remember or find the exact quote. Something to the effect of:

"Look around at all these things I have - how could I be wrong when I have so much?"

And that's how you get the Andreessen's and Musk's of the world stating these nonsensical things as truth. In their minds, financial success is the ultimate yardstick. The fact that they have so much wealth is a testament that their way of thinking is always right.

You don't need to look very hard to see this is what they really believe. Elon has done extremely silly things like claiming he was the best Path of Exile player in the world because he paid several people grind his account to a high-level. Having enough money to pay someone to play the game for you, is the same as being good at the game, in his mind.

> In their minds, financial success is the ultimate yardstick.

In a loopy recursive way, it is. Cost gates what we can do and become. Paying back your costs to extend your runway is the working principle behind biology, economy and technology. I am not saying rich people are always right, just that cost is not so irrelevant to everything else. I personally think cost satisfaction explains multiple levels, from biology up.

Related to introspection - it certainly has a cost for doing it, and a cost for not doing it. Going happy go lucky is not necessarily optimal, experience was expensive to gain, not using it at all is a big loss. Being paralyzed by rumination is also not optimal, we have to act in time, we can't delay and if we do, it comes out differently.
