Not sure that I buy the theory either at the macro level, but I think one thing I have personally seen/heard of is people who are now realizing how much they don't like the city life (even when things are open) and the pandemic is the straw to break the camel's back here and convince them to go elsewhere to try something else. The key is that it's not temporary for them.

Even the people that are there for work and already knew their city reality may also be realizing their gained happiness out of the city is worth more than the financial boost of their job in the city.
