Any thoughts I entertained about Tigger's credibility went right out the window when she said she was getting SSDI instead of SSI. In earlier posts she said SSI.
I used to work for social services. We did not administer either of these benefits b/c they are federal programs, we were state. But these people often came in for food stamps and other things. To the average person, who doesn't get these benefits, they don't know the difference but the people who get SSI know EXACTLY what they are getting and would NEVER mix the two.
For those who don't know, I explained this before in another thread, but I will do so again here. Both programs require a disability as determined by the Social Security Administration. This disability must be severe enough to prevent a person from making a living. SSA is very strict and almost always denies everyone on the first application. Both programs are administered by the SSA. Those are about the only things they have in common.
SSDI is what the average person is familiar with. Everyone who works gets that money taken out of their paycheck to pay for it. It is, as Vrai said, insurance. When you retire that money is supposed to be there. SSDI kicks in when you aren't old enough to retire, but become disabled and cannot work. Anyone who has worked for more than 10 years gets this letter in the mail every year telling them how much they'd get if they became disabled, retired, or how much their dependants would get if they died. You have paid for this all your employed life. When you are eligable for this you are also eligable for medicare because you paid for that too.
SSI is federal welfare. It is for those people who have not worked for the 10 years required to receive SSDI. In general, these people were injured too young to have worked much. In some cases, they were born with disabilities that have prevented them from EVER working. They have not paid into Social Security so this is not insurance. They do not qualify for medicare because they never paid for it. They DO qualify for state Medical Assistance, automatically without even having to apply.
