I do think downsizing needs encouraging via taxation, lots of widows by us staring out the window all day, not knowing what day it is whilst their money goes on cleaners, gardeners, maintenance companies for their 5 bedroomed detached houses in the catchment areas for great schools. It's not right whilst children are growing up in houses you couldn't swing a cat in. In my area, developers are busy building 5-bed detached houses because they don't cost a lot more to build but they sell for more. Meanwhile there is a huge shortage of 1,2 and 3 bed homes. If I were to downsize, I'd be competing for housing in short supply.
I don't mind paying a levy or whatever to fund social care. What annoys me is the lottery of it, person A has a degenerative physical illness and gets not just their nursing care but all their social care paid for, and their children inherit the house and any savings. Person B gets dementia and have to pay for everything, and their children inherit nothing. If we really feel so much against "preserving someone's inheritance", why not increase inheritance tax across the board and use that to fund social care.
Meanwhile we have the added unfairness that a self-funder in a care home is paying not just for their own care but also a massive whack towards the care of Council-funded residents.
And of course, we're all focusing on elder care, when half the social care budget goes on care for younger people with disabilities.
