I know there was some concern about people on SSI getting left out and I think it's ok for those people too although it may be necessary to file taxes. I'm not sure how you do that without income but someone who knows more about taxes than I do may know. Or maybe them having income and contact information through Social Security is enough? Government stuff is too complicated.
