Homelessness doesn't exactly sound "solved" in Utah... https://www.sltrib.com/news/2022/12/22/this-year-least-159-h...
In ten years, incidence of chronic homelessness in Utah went from 1,932 to 178.
Solving 91% of homelessness is a fantastic achievement, even if the remaining 9% needs further work.
The reduction was closer to 60%, and in the past few years, they've stopped investing in the program. It's been a good thing, but without ongoing effort and investment it will regress back to the mean.
