Canada

You'd be amazed how many people don't understand that causation. For example, most people I talk to IRL about this don't know that most homeless drug users started using after they became homeless. Instead, they think the homeless became addicts first and spent their rent money on drugs. Once they're made aware of that and the fact that a housing-first approach is actually less expensive than the costs of homelessness (shelters, law enforcement, etc.) almost everybody I've discussed this with agrees that ensuring everybody has housing is the best approach. Mind you, they will rarely agree that everybody's house value needs to come down, but it's a start.

That's a relatively small problem (in terms of how many housed people are acutely impacted or even aware) in large sprawled cysts like the GTA. The unhoused population is visible in small localized spots. The vast remainder wouldn't even hear about it if they didn't read the news or don't have to go to those spots. The very large city of Mississauga for example hasn't heard or seen a peep about unhoused people. It's only stories by the few that work specifically downtown. The backyards are as clean as ever and the birds are singing. I wish everyone was acutely aware.
