There's plenty of blame to go around. You can thank all the NIMBYs and countless housing regulations that prevent cost effective shelter from being created.
It's within our technological power to create housing for a tiny fraction of what it costs today in SF: just look at the tiny house movement. Just imagine how much cheaper it would be if something like that was built but stackable. Housing, A potentially multi-trillion dollar industry, completely unassailable, very few companies or investors are investing in this, all thanks to: Regulation.
Regulations and land use policy hamstring developers, increasing costs endlessly. Instead of working against them, we should be working with them to streamline and reduce their costs and finding ways to create more competition between them, to ensure that people get the very lowest prices. It can be done. Places like Dallas are growing every bit as quickly as SF/bay area and can still create housing for 100$/sq foot. I suspect even lower prices are possible with the removal of regulation: which would finally allow humanity to innovate in this area, rather than creating yet more cat video apps.
This harmful idea that real estate is something that should go up and up forever is wrong: morally and economically. In a world that is progressing, things should be getting cheaper, even real-estate.
Right now, your options in SF are a 200$ tent under a bridge or a 2 million dollar condo. There, really ought to be more options between those two extremes.
Say, did you ever read or see "Ready Player One"?

“Is the US facing an epidemic of 'deaths of despair'? These researchers say yes”
Don't get me wrong, I'm very aware that most moral systems have somewhat-principled reasons to prioritize those that are geographically closer to you. This is intended more to illuminate that side of the argument than as a full-fledged suggestion for how to set our priorities. But the claim being discussed here, that the future will wonder why we let people die in the streets, is still bizarre to me in the context that you're framing it in.
You argued that thinking globally is more important than thinking parochially, which is fine by itself. But it's totally unrelated to what toomuchtodo is saying unless we were taking global action in lieu of local action.
So I assumed you meant that, because it's critical to your comment being relevant.
If you didn't mean that, then your argument falls apart. toomuchtodo is not arguing for being parochial, they're arguing that we should be making it a priority to fight this problem at all.
I'll agree with you on the environmental issues, but I think we're well on the way to solving those too and largely via the same mechanisms, Chinese solar is close to pushing coal out of business on price. That's not to say there's no role for regulation in the environmental direction though, I certainly think there probably should be, but how to do so globally and fairly is a bit of a catastrophe.
Given the incredible amount of energy and resources being wasted by some of the richest countries this level of inequality is far from acceptable.
But I am even more afraid that our future descendants will live in the same rampant callousness and cruelty that we've created and perpetuated.
If they live in a better world than ours and look at us like savages, then I think overall things will have gone pretty well.
Sorry that it's all The Guardian but they had a series that I happened to remember, and I think that publication has a good enough reputation:

Of course, if we find the slightest mistake or hyperbole (if there even is any) in an article or comment about the plight of the poor we can discuss THAT instead and dismiss the entire thought. Another form of bike-shedding, instead of using good faith for the discussion use every tiny opening of the "opponent" to sidetrack the discussion and to dismiss the issue.
So, where are the people of the masses of dying in the streets? None? Even in San Francisco they look shabby but very much still alive? Well, case closed I guess.
If future historians look at any part of this with confusion, it'll be the part where we ignore mental health and think dumping cash/housing/whatever on a person will solve everything.
