I have seen another contributing factor in CS: it is really hard for the management to keep a good senior to junior ratio ie. A lot of juniors are trying to enter the workforce today. It means that during covid and shortly after the companies definitely relaxed as much as they could the geographical constraints for senior remote roles, also being senior they trusted them to work remotely not needing too much direct supervision. And now it backfires when your company is in silicon valley and you ask your senior developer from the boonies Colorado to move to an industrial concrete jungle.
