Unfortunately, a lot of the homeless I knew were very proud, arrogant, angry, bitter and many other emotions that made it nearly impossible to get them to take care of themselves through any intervention.
And if people refuse to take care of themselves, they will always be in a state where they need others to step in. Once they become destructive to society, I don't think any expectation of mercy from leadership should be expected. That leads to the situations we currently see in some places today.
It's not the lack of shelter that's the issue. There's plenty of shelter and housing if you want it.
When programming, when engineering, I often run into these sorts of intractable problems.
Changing the rules, changing the preconditions or some aspect of the problem itself, that's usually how I solve them.
In this article, it looks like the Park Ranger is changing the rules by making the system work for the person who is experiencing homelessness instead of forcing the person to go alone into a system that they don't like and they don't necessarily see the value of.
SO it is possible to fix with the appropriate smart thinking and willingness to maintain multiple simultaneous perspectives, it seems.
