It's late, I'm obviously not putting myself across very well here! 
Boo, I did say that earning opportunities could be the same for the older two people, at least I meant to. But for the people in the same houses, one renting privately and one on hb, there could be a variety of reasons why that could be. One could have a degree in a high earning job, the other may have been made redundant from their high earning job, or simply unable to earn enough to pay full rent. For whatever reason.
I realise two elderly patients could need different levels of care, but either way they still both need care, and imo, should still both get it.
I stated at the start of the thread that I can see both sides of the arguement. Part of me feels that I shouldn't have to pay higher taxes to provide inheritance for some rich persons children, but part of me feels that it's unfair that a house should be taken away from a family because it's owner needs care.
Bubble, I don't think that a person who doesn't pay for care should recieve inferior treatment, and I have said that already. I think it should work in the same way as education, quality care available to everyone, but if someone chooses to pay for something different then they can. In the same way that a person could choose private healthcare, or private education. But if they chose not to, then they could still access care.
