Elderly abuse is a big problem. Lots of companies target old people making them purchase stuff they do not need at all, it is regular companies, even banks, This is clearly a permitted scam.
Then, there is also family abuse. Some people use their retired parents as babysitters as if it was their responsibility. Most Grandparents Love to spend time with their grandchildren, but not to the point where it becomes a non paying daily job
They target my father in law like this. It is sad, but my wife and her sister don't want to take his control away - even though he has lost it himself.
I think it should be a paid job!
People who babysit their grandkids can get extra money for their retirement, so that the parents can concentrate on other things as well. A bit like in tribal society where the elders taught the young, while the parents hunted and gathered.
