I'm not sure if I buy the quality of life argument, at least in the context of the very well-paid tech employees. The "ambient" quality of life in many prominent areas has been fairly abysmal for years (since long before COVID-19) and these well-paid residents simply avoid this by Ubering from one isolated "nice area" to another. I doubt that incrementally less public funding for education, cleaning, homeless, and drug problems is something that most of these well-paid residents would notice. They'll just keep paying to maintain their "nice areas" and Uber from one to the next, just like it has been for the last 9 years I lived in SF.
