Every complaint I've seen on this topic is about how repulsive or unsafe it feels for someone commuting to their job in SF. No one talks about these thousands of people who are suffering from drug addiction, mental disorders, socioeconomic injustice, and all kinds of abuse. No one's complaint is: "how can we, as society, allow these conditions to persist, why aren't we helping these people in a meaningful way?" It's the apathy of the population in general that allows this kind of situation to come about and then persist despite the best efforts of "they" who are supposed to "do something about it."
