I receive social security disability, NOT SSI. I worked long enough to earn my quarters.
I have a friend (ex co-worker) whose SO never worked over the table, so never earned his quarters. He gets SSI and his check is almost double mine. He has a "back injury", but it doesn't stop him from playing softball, playing frisbee with their dogs or driving to Oklahoma three times a week to buy booze.
Because he gets SSI and they are not married (they won't marry because he'd lose benefits), he also gets food stamps, medicaid and rental assistance. They live rent free in a mobile home owned by his sister, but sister signed a paper saying they rent.
We won't get a COLA increase for the next two years, but our medicare premiums will still go up. Every year they go up by about the same amount as our COLA increase.
His medicare premiums are paid by Medicaid (the state).
Friend's SO will still be doing fine, especially with her full-time job. I'll have to be slower than I am now about having the money to pay the 20% doctor and hospital bills that medicare doesn't cover.
To me, in a nutshell that's what's wrong with social security.
