There are really two sides to the story here. Often what happens is quite different from the common notion of 'children not caring for parents and thus dumping them in old age homes'.
I have an uncle and an aunt (both in their mid to late seventies)- he suffers from various ailments including general memory loss while she is a full blown Azheimer's patient. One son of theirs passed away early and their surviving daughter lives in a far-away country with her family and comes to visit every year or so.
Uncle is adamant about not leaving the country to stay with his daughter because he likes the familiarity of his village and country and the daughter can't leave her family and come back in the situation.. She had been paying for a full-time nurse at their home but a nurse can't take of all needs. Uncle is often delusional and does insane stuff (he gave away thousands without realising who he gives money - he still accesses his bank account and has good savings).. Aunt walks out from home when nobody's looking and search parties have to be sent to find her..
The daughter was paying far more to keep a fulltime nurse who can't take care of all their needs than it would take to keep them in an old-age home where there is somebody to always watch them..
And yet the negativity associated with 'dumping parents' in old-age homes is what stops her from doing it when she can't take care of her parents herself.....
Recently the nurse left and they can't find a new full-time nurse to replace her.. if something were to happen to uncle and aunt, people woulnd't find out till it was too late because there's nobody around (they live in an independent villa within a large compound)..
The best situation would be to get them to live in an old age home (you have excellent ones that provide good care at the right price) but the stigma attached it is what stops the daughter from that drastic step..
There are many others who genuinely need to be in such an institution because it is in their best interests... especially when they dont have children or anybody staying with them.. And people need to realise that not all people living in such are are parents abandoned by children
