I suspect that elderly people don't move to one of these places because they are tricked into thinking that it will be better than living with family. I think your comparison is disingenuous.

I didn't say that. I said to fleece them under the guise of a more social, more fun environment which is exactly what the sales pitch was. To be around people your own age and do things people like you do, IOW.
And what was inferred by They would have been happier staying in their family home wasn't to be with family, rather that the home is filled with memories of life and accomplishment whereas a death every-other-week at the "village" was a constant reminder of our approaching end, even for the people who worked there.

I suspect you say this because older people require care which can be hard to provide at home. Fine. But many of the people who resided there were initially healthy and making a lifestyle change rather than seeking care. A side-effect of moving to a retirement village is that your progeny assume everything is dandy - you've got friends and carers, so they visit less often. The effect is devastating.
