Hi
If my parents have to go into care then they will pay for it from the assets they have, and quite rightly. They will have considerbale assets, partly because they have worked hard but also because they have profitted from a huge increase in property values. I don't see that money as my "right" to have after their death, as I've never earned it, and I'd much rather they used it for care to give them a quality of life. I think it's reasonable that they should pay for the care. If they didn't, then the people paying for it would be you and me through taxes.
The vast majority of people never need to go into care anyway, so it probably won't affect you.
