2. That's not the point: we're talking about a hypothetical shift where top software engineering talent is fleeing the bay area. If that talent moves to Ohio, and there is no cheaper alternative of similar quality, Google might not have a choice.
Again, not pretending like I know what's going to happen. My point is that big-tech doesn't have total power in setting prices. If at any point in the last 20 years they could have hired qualified engineers in Ohio for $100k they would have already done it.
