The "4 out of 5" figure roughly matches what I recall being told by a head of Catholic Charities maybe a decade ago. You certainly have some percentage of people who’ve been given everything they need to be comfortable, and when you leave them alone and come back to check on them, they simply have not been able to look after themselves. But for the vast majority, it does work. People are in a safe space where they can look for work, have an address to put down on applications, and all that.

Quite affordable too; ambulance rides and jail visits aren't cheap.
