As I say, unless people have a family...and that makes them reliant on someone else, which creates problems. We'd like to be self-sufficient and independent. It does not foster that kind of environment.
I would also suggest because of the baby boomers retiring, as was previously said, this problem is going to be more prevalent in the near future. Not everybody has family or friends here. They're shut in to begin with; they just can't get out.
