I understand what you are saying regarding patience and resources. But if Medicaid were to cover home care, as you suggest, I suspect many would opt for home care care for their older family members at least initially.
But it doesn't, so when our parents get to that point of not being able to safely care for themselves, we are faced with (1) keeping them at home and providing 24/7/365 care by ourselves, (2) letting them stay at home and using whatever monetary resources they still have and we might be able to contribute to hire nurses and aids to care for them, (3) put them in a nursing home and take advantage of the medicaid provisions (which would not take effect until after every last dime of their assets have been spent first.)
