I agree. Add the absence of a healthcare system to that too. Personal anecdote: a homeless man offered to wash my car for money. He seemed intelligent and nice, so I agreed. He told me the story of him becoming homeless. Both he and his wife worked and rented an OK place in OK part of SF. His wife got into a car accident and their crappy insurance couldn't handle it, the deductibles were astronomical because, as usual, some of the "independent businessmen" who "provided care" were out of network, as if the unconscious victim had any control over who touched her.
So they had to drop their income below certain level to qualify for free healthcare. Now he didn't have enough for rent and moved to under a highway bridge and was visibly embarrassed by it.
When people are talking about Seattle's worsening homeless problem, they're talking about the presence of needles and fecal material on the sidewalks, and being harassed, and sometimes even attacked, by clearly mentally ill people, not about people living in trailers in non-urban areas.
Officials need to address the whole problem, not just the visible problem.
So, if we prioritize, say, addiction treatment, more people will want to be addicts. Right.
