If the day to day living conditions were actually acceptable, many people would have stayed during the pandemic. The real problem is the sky high cost of housing with a low quality of life.
I put up with increasing crime, dangerous grime (such as needles in bike lanes) and tent cities on sidewalks all over the place for a decade until my brain couldn't take it anymore.
I have no problem paying Zurich level prices to live in SF due to its surrounding beauty, great opportunities and people but the mismanagement of the city has proven the high costs do not come with high quality of life.
I would share more but I'm typing on my phone, I'm just disappointed to see "techies" still being blamed and called money hungry just because people are looking the other way at other problems.
