I guess I'll throw my anecdote in the pot. I used to live in SOMA Grand, the condo building sandwiched between the Federal Building and Trinity Towers, right around the corner from this Whole Foods. I left SF around 2015. I recently walked the neighborhood and
holy shit it is much worse than I remembered. There is a methadone / treatment clinic on Minna, the alley between the Federal Building and the condo. So there's always been a few people coming or going from treatment, and a tent or two. But this time there had to be a hundred people or more crowded in the alley, hanging out on the steps of the Federal Building, and so on. I'm not sure if they were all there for the clinic but nobody seemed to be coming or going. People were openly burning trash on Market St. like some kind of dystopian 80s flick. I used to see active drug use maybe once a week; this time I saw it half a dozen times in two blocks. Maybe it has not changed in the last year or two, but as a former resident of the exact area under discussion, and one who's not unsympathetic to the plight of the homeless, the area has become unliveable.
I often miss the City and have found myself questioning the choices that led me away. After this last visit—no more!
To your point, I wonder if it is "boiling the frog." Maybe things didn't change that much in the last 2-3 years, but they sure have in the last 8.
Taqueria Cancun still slaps, though.
