Is it though? I feel SF is a rathole that is occupied by a lot of people who overpay for rent because their salary allows them to.
If you're really wealthy, you're not going to be living in the city at all.

Huh?
Are you talking about the same San Francisco as everyone else here?
The rich live in San Francisco, the wealthy live in Napa Valley / Sonoma County. Can't fit a helipad, two tennis courts, putting green, and an olympic size swimming pool downtown.
The wealthy have their own very large islands. Islands that are very likely nature preserves. They don't need Napa Valley. I can assure you though, that the wealthy also have homes all over the world. And I guarantee you that crappy cities that smell like pee, such as London, San Fran, and Paris, are on their holdings list.
That's just the way it is, cool kids want to hang out with cool kids. And when they're not, they want their privacy.
