FWIW I blame systemic problems not the individuals responsible. But the problem was viscerally apparent to me.

I reported some shit for the city to clean up. They never cleaned it up. It just sat there for weeks decaying. After weeks, there was only a little bit left... probably ended up on someone's shoe.
Early in the pandemic, the city looked worse. Now it looks somewhat cleaner but still depopulated.
There are some tourists but surprisingly many of the people walking around at Bay Area locals. The tourists are still so few that you can recognize them upon seeing them again.
There are few and dwindling public bathrooms to the point where gig workers struggle to find facilities[1] while they're out there doing critical work. Rich NIMBYs believe that bathrooms (and not the sky-high rents they seek) encourage people to become homeless, so they've successfully shut down the emergency facilities opened up during the pandemic[2].

I was attacked by a disturbed man who chased and pulled a (probably fake) gun on me, but no piles of shit whatsoever!
Speaking from experience of daily driving through Tenderloin.
