Must be interesting to work with people relocating and hear their reasons for doing so. As I wrote before, even though nobody, myself included, likes an influx of people from out of the area moving into their town (increased market values, more traffic) I can't blame people from places like California for moving somewhere more affordable; I'd do it myself. I wish I was drawn to, say, rural Missouri as real estate is so ridiculously cheap there....but I'm not.
Having grown up in the Bay Area I've seen, as you mentioned, people moving to smaller towns outside the Bay Area for purposes of affordability. But really it often doesn't solve all their problems as they then often commute back to where they moved from for work. So now they're spending more time in that atrocious traffic (main reason I left) and paying more for gas, etc. I don't know how familiar you are with the Bay Area, but all towns connected to it are very expensive.
