US domestic competition is a concern, but my hunch is that even with the wider talent pool companies will still have trouble recruiting and good developers will still have leverage over not needing to move. I think it would be interesting to find numbers on how concentrated developers are in expensive cities, I know plenty of people who moved to California for the work.
Also, if my wage suddenly decreased to match levels with places that are cheaper to live in I’d probably have to move away from all my friends and now family as I wouldn’t be able to afford to live where I currently do (SV). That would suck, and I think it’s fair that I feel concern over losing that. Not sure where all the negativity in this thread is coming from.
