Supplemental Security Income (SSI) is a Federal income supplement program funded by general tax revenues (not Social Security taxes): It is designed to help aged, blind, and disabled people, who have little or no income; and It provides cash to meet basic needs for food, clothing, and shelter.
Sure sounds like a disability program to me. Yes, it is for people with limited resources and income, but it’s not welfare for anybody, you also must be disabled, old, or blind.
I've been on it once. It's been 25 years so I forgot a few things. Actually my wife and step kids were eligable I wasn't. We used it for about a year when my wife first went quad till I could get my wife stabilized and family trained so I could return to work. Our combined disability monthly income is about $1400 so we don't qualify.
