Thus Mom and Dad could "work the system", stash the cash in a policy that would pay out on their deaths to their heirs someday and in the meantime, they could get a free ride on Uncle Sam's dime at (hopefully) a nice Long Term Care facility somewhere.
There are philosophical opinions on whether this practice is corrupt, or whether it is actually honorable.
The corrupt argument says that it is wrong for anyone not to pay their own way through this world, especially if they have the means to do so.
The honorable argument says that one should have the right to give away ones own assets to anyone they choose, especially loved ones. It also says that one who has served this country well and paid taxes deserves a government funded LTC ticket.
This argument rages to this day, however, in the current era of budget deficits, there simply will not be federal funds for most seniors needing LTC help.
