@Kryptonite, over many years I had a lot of experience of visiting several care homes (3 relatives with dementia, one just frail) and they were all very good. I would add that a lot of care was taken when choosing the homes, though, and the most expensive ones certainly did not strike us as the best.
The two that gave me the very worst vibes were at the top end of the cost scale, though ‘plush’ at first sight. The general aura was of cash registers ringing, so to speak.
Particularly where dementia is concerned, I soon came to view ‘stylish’ decor as a means of winning over the relatives who were doing the choosing.
As for what they do in ‘other cultures’, in many countries people have no choice, not to mention that with less access to health care, because of distance or cost, people may well not live as long. While working in Cambodia a dd witnessed a grandmother with dementia, in a poor rural village, being tied to a chair outside all day, to stop her from a) wandering off, and b) messing the house with her incontinence.
The family would hose her down once a day.
We have Indian friends (in Mumbai) - the wife told me that it’s rubbish to say that in such a society people invariably look after their own. Her own mother (with dementia) was looked after in her own home 100 miles away, by two live-in carers, an arrangement (as she said) far cheaper and easier to arrange there than it would be in the U.K.
She added that such arrangements were common with those who could afford them - and you didn’t need to be particularly well off.
I also have a non Brit SiL from a Mediterranean culture, and my BiL used to say how wonderfully people from her culture looked after their elderly.
Fast forward to when FiL’s dementia was making him very difficult to cope with - SiL refused point blank to have him any more (I was doing the vast majority of it) and told me that in her country, he’d be in a home, and given drugs to make him easier to cope with.
