I have always considered it quite reasonable for the value of an estate, including the house and all savings to be used for our care. Our DC have no divine right to inherit assets, particularly when many people are too poor to leave their children anything.
The luxury that having assets gives you is being in control of what care you get and where you get it. When my sister died suddenly, after the grief and the sorting of the estate, she died intestate, when the money was being sorted, our parents kept some of the estate for themselves (they were entitled to the lot), explaining that the money they kept would ensure that they could pay for any care they needed, and what a relief that was to them.
