(because of the things I described above about how california privileges long term residents, I actually don't pay much more here than I would in any other place of similar density, and net earnings, I'm way better off financially here than anywhere else because I have that granfathered housing deal. (of course, my housing here is a lot less flexible.) Nobody else in the world will pay what silicon valley will pay when you have my skills and no degree. But in theory I would pay a premium to live here.)
Before I die, I want to try living in New York, partly 'cause I really enjoy the car-free lifestyle, but also 'cause I think that it's good to sometimes go to a place where you don't fit in as well, where you interact with people who have dramatically different worldviews about what constitutes an interesting problem. But for me, someone who fit in really badly where he grew up? Finding a place where I fit in was supremely important, even if I don't think it's great to spend the entire rest of my life in that place. Just having that experience of fitting in is transformative, I think.
My guess is that actor/entertainer types have similar feelings about LA; I mean, I think there's a lot of stories about that; about young theatre types running off to LA to find themselves (which I assumed meant "find people who value you") I mean, people talk about shared values; and it's not about voting the same way, mostly, or anything like that, at least for me, as it is about finding the same sorts of problems interesting. I mean, acting and entertaining is a deep sort of thing. I certainly don't understand much of it, but I can at least see that there's a lot there to understand, and if that's your bag, it seems like going and living near other people who also find that sort of thing could be important.
