I am not surprised with this either. My elderly mom lives with my sibling. She has money for 24 hr care, but she has only kept a lady attendant who comes from morning 9 am stays till 4 pm. My sibling has a whole barrage of part time employees - daily cook who comes for an hour, daily cleaner to clean the house and do dishes, someone to water the plants and take care of the lawn etc. We have CCTV all over the house and in all rooms.
We make sure that periodically we invited relatives for meals etc so that they can meet my mom and her brain remains active. The one thing we do fear is the greed of people working for us. So we live a simple and pared down life. There are no valuables at home that can be stolen.
