What ever we are currently doing to solve the "homeless" crisis, it isn't working. Time for some new ideas.
Ultimately, I don't know what can be done to address it that wouldn't incentivize other people to milk the system, or that wouldn't be labelled "mean" by half the country.
If involuntary institutionalizing (for mental health and/or drug addiction) is off the table for being considered "unfair, and infringing on their dignity"
And trying to put 800k people up in no-strings attached "we'll pay your cost of living forever" arrangement isn't feasible and would lead to abuse (which it would)
Then we don't have a lot of options in the tool belt.
There are a few key statistics that shines a spotlight on what I feel needs to be explored more:
A 2016 study of homeless adults in Los Angeles found that around 40% had some form of family or friend connection but chose not to live with them.
And according to the National Alliance to End Homelessness, among homeless youth, 30-50% come from homes that were relatively stable before becoming homeless.
Especially on the "youth homeless" homeless front... there should be some sort of process or something that dictates that if an LEO comes across a homeless 17 year old, and there's no proven reason why they shouldn't be returned home to their parents, then that's what needs to happen. (and by valid reason, I mean things like abuse)
If there wasn't abuse happening, and the reason they skipped town was "I wanted to be able to do whatever I wanted drugs/sex/etc... but my parents wouldn't let me because they just don't get me man!", then that's not a valid excuse, sorry, you're going back to your parents' house in Iowa.
And if the reason they're opting not to live with the friend or family member is because and offer was made, but stipulated with "but you're not going to be doing hard drugs while you live here", then mandatory drug addiction treatment is the solution.
