Turns out if the environment of policy finally says "this is bad" it tends to start cleaning itself up. Previously the policy was "this is good and allowed".

The weather improved?

Even trivially small amounts of homelessness make a place feel much more desperate than it is.

One of the things people don't realize is that the per capita homelessness is often higher in small towns and rural areas - you just don't notice it when it's a van parked out in the woods. But 5 tents on a city street disproportionally gives worse vibes.

Believe it or not, European countries like France and Germany actually have much higher rates of homelessness. They just do a much more thorough job of policing it and pushing it to the periphery of urban areas. (Similar to what is now happening with anti-camping laws) So ironically America has done much more for homelessness than other places despite it feeling the opposite because of how public it is.
