Would you rather be an elderly Jew in a Florida nursing home in 2005, or a healthy Jewish child in Poland in 1940? Take your pick.
The key was in your first sentence, having a surviving loving family who could oversee your care.
It's not an easy choice, and I don't mean to be crass. Florida does not sound like a healthy place to be elderly or disabled in, but that is by no means the only place. Something could happen so your loving kin would not be there for you as you plan or hope. There are many elderly who have no living kin or irresponsible kin all over the country.
Many are dying alone and unloved by anyone. Some have children who have forgotten them or have taken no repsonsibility for them, and social services has to find housing for them, etc.
Poland was probably worse. In either place, you couldn't be sure who wouldn't turn you in though. It has NOT come to that by any means.
I'd rather be a healthy Jewish child in Poland in 1940. You at least have an outside chance of escaping that. There is no escape from being elderly (anywhere) and in a home save death.
