A lot of the young ones are either escaping sexual abuse, thrown out by their family for their sexuality or rejection of religion, or aged out of foster care.

There is indeed a spectrum of homelessness from temporarily distressed to broken beyond repair. There's different actions for the different factions.

I live in the Portland OR metro and believe that the issue has spawned the Homeless Industrial Complex that thrives on extracting money to "help" but are incentivized to keep the problem going for their livelihood.

I'm not unsympathetic to their plight (I had been effectively homeless a couple times in my life). It bothers me to no end how this problem is mismanaged.
