Once we became a post-industrial and much more mobile society (IBM standing for I've Been Moved, for example) the safety nets of many extended family members living adjacent to or at least relatively nearby has diminished to an almost non-existent state.
And, absent great wealth on the part of a willing fmaily member of the elderly person(s) themselves, someone has to step in and assist. On the one hand, it is not, constitutionally, the governments' (Federal, State or local) role or obligation to provide services, to the extent it is (1) Necessary, (2) affordable and (3) possible services from the government, or even better, local religous and chairitable organizations, assistance can be provided that takes care of the minimum needed to maintain quality of life. Programs like "Meals on Wheels can be a hugs help to the elderly housebound and those programs receive the bulk of their funding from state and local governments and organizations and not from Federal funding so they can and should continue to exist.
Their are local transportation programs that can help get elderly folks to-from medical care, grocery shopping or the malls, etc. And those are very useful especially in areas where public transport is not readily available.
Assistance with managing administrative things like bill paying, doing taxes, etc. can be done but require a level of caution and oversight as thgere is high potential for fraud and abuse.
Basically, my belief is that we have an obligation to be self-sufficient and not reliant on government; but that at some point, that may change and if we have been responsible, productive tax-paying citizens then we have a right to expect some level of assistance to maintain a reasonable quality of life.
It is the elderly, the few survivors of the great depression and WWI and Korea that built the current economy and industrial and medical base and infrastructure. We owe them a debt of gratitude and respect that can never be fully repaid but that should include reasonable services to maintain their quality of life and dignity as they still have knowledge and experience to pass on to us before they leave us. Keep them always in your minds and prayers as you give thanks for what we have and what the future can be as we move forward to restore American greatness and world leadership.
