It's certainly widespread, but it's not ubiquitous. I live smack in the center of the US, and visited Hawaii in ~2000. I remember being pleasantly surprised how little people cared about that sort of thing, and was far more comfortable on the beach there than anywhere else I've been. I was with a group of locals, not tourists, so I assume it's a cultural thing.
