Market St. is a war zone.
The city spends $300 - $400 million a year on the homeless industry, but virtually none trickles down to the actual homeless.
I would agree that two slums sandwich this narrow band.
Trickle down doesn't work for people who do not contribute to the society in any way. Why do many homeless don't? I don't know, but that's what any government effort should focus on. Spending money and hoping it will trickle down without addressing the root cause is stupid.
There is currently a well-funded political campaign, backed by VC money, to change conservatorship laws in California to snatch homeless people off the street and involuntarily institutionalize them. You are doing serious harm by allowing people to spread misinformation here without challenging them, and punishing people doing the thankless work of correcting them.
