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.
In 2004 the homeless made up 1.15% of the population. In 2017 it was 0.08%. A 30.5% reduction. Definitely significant.
I see two issues that are driving the false perception regarding homelessness.:
As you reduce the overall homeless population the significantly mentally ill and drug addicted make up a higher percentage of the homeless that remain.
The policies enacted have concentrated the homeless into fewer areas which makes it seem that their numbers are higher rather than lower.
Just like our current national hysteria around crime or immigration, the notion that homelessness is somehow getting worse, or that San Francisco is doing a bad job handling it, are flatly contradicted by the data. San Francisco is in fact doing a better job handling homelessness than most of its peer cities in the United States.
Readers of Hacker News should go to the data first. Matier & Ross have a long history of this kind of ugly sensationalism and it has no place here.
