Sorry. But you're either misinformed or actively malicious here.
> US HUD says it's ~16% of homeless people
It absolutely is close to 100% of _unsheltered_ people. Some social workers helping the unsheltered homeless are now saying that they have not seen anybody who's _not_ on drugs or who is not mentally ill.
If you want authoritative source, here's UCLA study from the blessed pre-COVID era: https://capolicylab.org/wp-content/uploads/2025/11/Health-Co...
> The biggest problem, unsurprisingly, is housing cost.
No, it's really really not.
> The US GAO states that a $100 increase in median rent correlates to a 9% rise in homelessness.
And the correlation disappears when you look at the states with cold climate.

Which specifically leads with a page saying:
> Hundreds of studies - including our own - show economic pressures are the primary drivers of homelessness, that housing people ends homelessness, and that targeted financial assistance helps people at risk of homelessness stay stably housed
Also, the cited study blatantly does not show the numbers ("close to 100%") you claim it has, even leaving that aside. You're also now equivocating between drugs and mental illness, as well as between drugs and alcohol. And you're not taking into account the direction of cause and effect (e.g. which came first, the homelessness or the addiction).
I understand that you're also referencing anecdata from social workers. In those cases, there's an inherent bias: people with a drug problem are going to be harder and more memorable cases, which makes them feel like a larger proportion than they are. People homeless for economic reasons are likely to loom less large in people's minds than the times they dealt with someone who had a drug problem.
