It's always best to avoid piggybacking on someone else's very old thread and posting your own new question. Someone may disregard yours as just another response. That said, you haven't asked a question.
(I hope you aren't saying that your husband got disability because he received a liver transplant, but because he cannot work due to long-term complications from it. My red flags always go up when it comes to vague reference to reason for disability. It's not personal.)
No one is saying X is right, but your reference to "Domestics" is a bit fuzzy and I presume you mean his SSD when you refer to "benefits".
As for wanting to help change laws, seems like follow-up may indicate that's not necessary (but if so, the place to start would be your legislative representatives).
