I read the premise of that book and it doesn't square with what I know about rich people from personal experiences with them.

What I've learned is that money is a multiplier for personality and if you have a humble personality, then you'll stay humble while you're rich (with some caveats about people that are not truly humble).

I agree with you completely on the humility, that's the only ones I would best be involved with, but these are not the ones who make it into this kind of book.

The emphasis is on the extreme, privileged and over-the-top attitudes stereotypically encountered.

Fortunately, exclusive communities with these stereotypical aspirations are not as overwhelming as they could be.

It's a small book, largely true quotations, and I think worth reading as an entertaining way to refresh awareness of peculiarities that can arise as riches are struck or wealth is created or increased.
