The undercurrent to this in my mind is that more of the middle class (and possibly upper middle) will move out. It actually already happening. The rich and uber rich will always continue to move in. If you have the means it is a great place to live. It was always more expensive place to live but not at the level it is now. In 10-20 years (pick a timeframe..) it will be all (or mostly) the rich and the diversity of this area will suffer. Coastal / bay area CA will always be desirable - it will just be unattainable as a permanent residence for those of normal means at the rate we are going. Most people here are in the tech sector and probably(most here or many) are at the upper echelon of the industry in skill and salary. In that bubble I think it is harder to see what the average person here struggles with on a daily basis and why they are leaving... Or even what the average "techie" not making 250K+ experiences.
