What evidence that was presented in the article leads you to that conclusion? I couldn't find any.
When families consisted of parents, several children, aunts uncles, cousins - family members rotated the care of their elderly patriarchs & matriarchs (Japanese still do). It is a cultural thing - and we have lost that culture.
My family hasn't.
This comment leads me to believe that she has not.
***I would gladly take my mother back into my home, but I don’t think it’s feasible for her to continue to live there. If we can manage to get her down those same steep stairs and into the house again, she’ll be trapped there indefinitely, unable to go to the doctor, grocery or anywhere else except to the hospital if she falls and injures herself again. And she’ll need someone with her 24 hours a day.***
You are blessed to have a wonderful family that still holds to the tradition of caring. (Please adopt me;)
