I look at this issue and see a market failure. Maybe it is not corporately profitable to provide the pile of services that a population aging in place need (welfare checks, transportation, food, housing...) but it should be possible to build the infrastructure to create the raft out of parts of a solution. Maybe a mix of formal (paid-for) and informal (volunteer, value-add) services. I see this as a necessity for people that do not at the moment face this "cliff". After all, spouses die, children leave and/or live far away. Any person in a stable situation at the moment could easily find themselves in need of these services.
