The only case where residents would be unhappy is when said residents flood the market causing meaningful inflation across local markets. It takes the entirety of the bay area young professionals to keep the bay area as expensive as it is.
1. Would the dispersion of the same talent (assuming talent isn't suddenly growing in size) + local tech talent being paid higher cause the same inflation even when split over a large number of cities?
2. If said inflation happens, would they not move again?
I believe incentives here are to distribute this talent across the US, not concentrate in new cheaper centers
