I think there’s a massive difference in what are for instance supported accommodation homes, resedential homes and care homes. My mum died in a nursing care bed in March riddled with cancer on a syringe driver. Couldn’t really expect family to look after someone who was that heavily dependent on nursing care. Same with end stage dementia. You can’t expect a family to look after someone 24/7 when they’ve got kids/jobs etc and don’t have the specialist facilities.
My Mrs’ grandmother was in supported accommodation and said it was the best thing she ever did at 88. Got to play bingo everyday, sit with ladies her age and discuss interest and went on days out.
Now of course, there is also the shite side where families simply stick relatives in when they can’t be arsed, but again there’s usually some form of capacity assessment before this is allowed.
