It's fine for him to invoke sympathy to encourage others to help him or others directly. This is not the mechanism that he's advocating, however. He's putting a human face on a huge uncaring federal bureaucracy that cares not a wit about anyone. So when he uses his disability to support a government that will compel me to submit to a government bureaucrat as to what I can buy under penalty of law, I find that despicable. It may well be me sitting on the ground in front of someone pleading my case someday. I just know I don't want it to be in front of some government official, because I know in that case no will mean NO. Ever dealt with the government? I have..."we've considered your appeal, and your case is denied".
Yes I’ve also dealt with unfeeling bureaucracy in a government, with people who stuck by their rules and that was it. With a tax system so complicated I can’t understand its written communications and then penalize you. With waiting for a response or a phone pickup or a turndown. Yes.
It may well be you or I sitting on the ground someday, unable to work, lost our home, in pain, too weak to stand, and we’d have someone come over and berate us for being a lazy bum for not working. But do we want a strong safety net there or not?
BTW there is an “opt-out” of the Law for states that decide to develop their own program.
