Kanye is both a cultural icon, and also regularly sounds unhinged. That’s not a value statement, just an observation.
West has billions, is a recognized musical genius, is now setting fashion trends and will go to bed tonight with Kim K.
I'd say he's doing pretty well, compared to most.
Sure, the crazy people who made a bunch of money (or the terrorists) are the ones you've heard of. The majority of "unhinged" people are probably not better off for it.
Steve Jobs is kind of a great example. On HN people fawn over him, but he was "unhinged:" he was a giant asshole to everyone, by all accounts, and he opted for snake oil over medicine during the earliest part of his cancer treatment.
Plenty of people get lucky and strike it rich or contribute meaningfully to society without being unhinged. There is no meaningful correlation here.
