in the long run people take care of their parents and you will not hear of older people being alone let alone die alone.

You are assuming these people have children at all - that's becoming less true every year.

Also, you should consider that people sometimes prefer to be alone. My grandmother now lives with my mother, but that was only after she fell at home at 85 years old, because before she preferred to live by herself. Had she died in that fall, she would have died alone too, but not because her children didn't want to take care of her.
