I also thought there would be specific examples leading to concluding paragraph.
Anecdotally, I do know someone who is disabled and after he changed his address he stopped receiving payments completely, and it took about 18 months to reestablish payments and every time he talked with someone over those 18 months he had to completely re-explain the situation and how many times he had already changed his address just how they were asking him to within their system and confirmed with the last person that he had talked to that he had changed his address in their system but had not received a single payment since the first time he changed his address.
At the end of it they finally confirmed that he had been missing payments for over a year and they would start trying to reimburse him.
He lives with his brother who works so he wasn’t homeless, but if he hadn’t had family, then the system could have easily killed him.
