Doesn't seem like mid-90s property appreciation in Seattle could have been pinned on Californians anyway. Wouldn't it have been more related to Microsoft, a gigantic and extremely successful company with an in-house Porsche dealership among other perks?

I see a similar defective thought process right here in Berkeley, CA. Everyone here blames housing demand on peninsula companies like Facebook, Apple, and Google but it's a fact that employment right here in the city of Berkeley has been allowed to double in the last 30 years while the city built zero net dwellings. We can try to blame it on distant villains but the gentrification, to borrow a meme, is coming from inside the house.
