If San Francisco is in a doom loop right now, what was it in back in the 60s-00s? An ultra-hyper-mega-doomloop-of-death? Hell in the 90s the violent crime rate routinely topped 1,800 per 100k. Today it is 1/3rd that. I remember San Francisco in the 90s. Today's San Francisco is Disneyland compared to then. My theory is that we are all suffering from collective cultural amnesia and have forgotten that the world existed prior to 2019 and thus have forgotten that while things go up and down year-to-year they have been getting better on the whole for decades.
