No one wants to do the most obvious thing - root cause analysis - and admit that the current system is broken.
Society isn't collapsing, it is excluding people from participating in it if they don't meant the "performance metrics", don't get the support they need, and can't find solutions to their problems.
In many cases, people on the streets are not there by their own choice (there are some who claim it to be so) - but there's one thing that legislators never really ask themselves - what caused this person to find themselves in this position, and what can I do about it?
