We are looking at the same thing but through different lenses. It is true that most of the current management layers are inept at managing remote workforce effectively. But they are capable of managing an in-office workforce - that's how they got promoted in their positions in the first place (mostly).
Guess what is easier decision for the decision makers - change their own skillset and habits, or force everyone back to office?
Funny you mention Vancouver, which I used to live in and, talking to tech folks there, it was routinely called the "H1B holding pen" at the time - the place tech companies would hire folks and bring them to work at US wages while awaiting visa paperwork to head down to, say, Redmond or San Francisco. And BC famously has a huge brain drain to WA and CA on account of - you guessed it - salaries, and those folks often never went back to Canada. Back to: the talent concentrated here and demands a certain wage.
