IIRC, I think around $750 to maybe $1,100.
I know a guy who is on SS disability (worked as a baker and messed-up his back when an 80lb. sack of flour fell on him).
He says SSI pays him around $700/month. And it sucks because he’s much rather be doing a job that he loved which paid him $21/hour.
On the other hand I know another guy who was a union tradesman who went on SSI. Can’t figure out what his disability is because I always see him working on cars and hanging Christmas lights on his roof. I am sure he used to make much more than $21/hour. He now spends his days drinking beer and watching porn.
My godson gets $130.00 in food stamps and $240.00 in disability. His medical care, such as it is, is “free”. He is 28 and has been mentally ill since he was a child, OCD and bipolar. He is also delusional, seeing trolls looking in his bedroom window at night and watching him from behind shrubbery and through walls when he goes out. He lives with his widowed mother.
