Not every homeless person is mentally ill. Even those that are weren’t necessarily that way before; being homeless is not great for your mental health. So giving them a place to live would be an unequivocal good for all of them where as what you’re suggesting only really helps a fraction of them.
Reopen asylums if you want, but they aren’t going to stop being homeless once they finish their treatment. Unless what you really want is just a pseudo prison to lock them all up in so you don’t have to look at them.
80% of the chronically homeless have life long mental health issues, and 60% of the chronically homeless have drug addictions.
Mental health issues caused them to be homeless. People with severe Bipolar, borderline, or schizoeffective disorders can’t function in society without being heavily medicated, and a choice was made to not take that medication (I don’t blame them. Anitsychotics have super shitty side effects).
Sure, homelessness might make it worse, but their illness is what led to the homelessness.
What percentage of people with lifelong mental health issues are homeless? What percentage of the housed population has lifelong mental health issues? Should we lock up the ones with houses in asylums too?
