The government assistance for these situations is often not enough to live on as it is (at least where I live), so I'm not sure how moving to this would be a negative. Also consider how difficult it is for someone with a chronic illness to actually find and access the myriad of services that provide the support they need, and at the end of they day it's still usually not enough.
It would be a shame to not move to something better for those people simply because it isn't perfect.
