No, I’m not “OK” with it - but I don’t expect mentally incapacitated people to act like functional adults because they are unable to do that. It’s like screaming at a legless man because he can’t tap-dance.
The crazy people stumbling around alleys, eating out of dumpsters, wearing tin foil hats and muttering to themselves are not doing that to piss you off or game the system or because they;ve made a conscious decision to stick it to The Man. They’re doing it because their thinking machinery doesn’t work right. It doesn’t matter if their brain broke due to injury, disease, trauma, or what have you - they’re disabled and we don’t have a good fix for a broken brain.
I’ve got a nephew who suffered brain damage and if it weren’t for an insurance settlement and a trust set up for his care he’d be wandering the streets homeless. He set himself on fire once and no one can say if it was an accident or deliberate (fortunately, because he’s in a protected setting, mostly just his hair went up and he suffered no serious long-term damage) . He’s in a safe place where he’s cared for, even if he’s unhappy about his situation, but that’s because there’s money to spend on caretakers and a small apartment in an assisted living complex and to make repairs when he wrecks something. Which he does from time to time because his brain isn’t working right, he can’t focus, and he has trouble with self-control Locking him up in prison isn’t going to fix him. Putting him in a “camp” isn’t going to fix him. Forcing him to get a job isn’t going to “fix” him (he’s had several jobs since his accident, but even in a “supported” and supervised circumstance he is unable - not unwilling but unable - to work). NOTHING is going to fix him. So… what is to be done with him? He LOOKS like a perfectly healthy young man - and physically he is. He looks like exactly that sort of person you’d have a fit about “not trying” and being “lazy”… but he’s not. He’s disabled. Meaning unable. Not able. It’s not that he won’t but that he can’t be an independent, functional adult.
The sole difference between my nephew and a lot of the chronic homeless is exactly one thing: money. He got a settlement that will provide him a place to live for the rest of his life. The guys on the street have nothing outside maybe a few socks and a shopping cart of stuff. All the types of coercion you can come up with to “fix” a person with a broken brain is not going to work, such a person is never going to be a productive, tax-paying citizen.
What you propose to do with such people says a lot more about you as a person than I think you realize.
