I'm reading Gioia's history of jazz right now, haven't gotten past the swing era. But one impression I've already made is that there was a period of time when someone could aspire to a modest but decent enough middle class life as a musician. I think that I grew up at roughly the tail end of that era. As for trends in the movies, I'm not sure they're related.
