Full disclosure: I work in a library shelving materials.
This take overlooks one of the factors that really needs to be addressed: mental illness. I have seen people without full control of their faculties outright refuse assistance because for whatever reason they believe that what they are being offered isn’t good for them. Some of them want help, but some of those also want help on their terms, which is not how a lot of social/outreach programs work. And that’s not even getting into the issues of substance abuse that act as a black hole for any material gain. Granted, there are people who will jump through any hoop to escape being homeless, but many who suffer the most really need more than just a place to live; they need to completely overhaul their lives, and our social system isn’t currently designed to do that.
Basically. I think there are certain cultural aspects of Russian society that are stuck over a century in the past. Unless those things get brought closer to the present, their society won’t change; we’ll see this whole thing play out again in the future. The average Russian citizen needs to see that the West doesn’t want to destroy them, that life can be better than what they currently experience, and that the world doesn’t need to be as harsh and demanding as the believe it ought to be. That’s a tall order though, so there’s no telling if that can happen in the near-future.
