I think the point is, you can lead a horse to water, but you cant make them drink. If people don’t want to stop using drugs, then they won’t.
Free healthcare, free counseling, free clean drugs and a generous social safety is clearly not going to solve this problem.
That's substantially moving the needle.
The level of human misery seems about the same to me.
I argued that the state of the homeless is no different (because OP argued "you just need universal healthcare and the problem will be solved). People putting up tents in the street, people overdosing on the sidewalk (did you know 10,000 people have died from overdoses in Vancouver to date? [1]), people suffering from untreated mental illness, people suffering from serious medical issues.
The point is not that Vancouver and SF have the same number of homeless, it's that the areas where the homeless are don't look all that different in terms of human misery.
Not that I'm suggesting Canada is some kind of model implementation for how to utilize social healthcare in assisting homeless citizens addicted to drugs.
My main point is before you have resources to even get to fail to use successfully in treating what is a social health problem, we need a damn socialized healthcare budget to even try make mistakes with.
The US can't even manage to treat healthcare as something every citizen needs let alone start caring about the citizen addicts in the streets as sick people in need of medical help.
