Emotional support can be provided only by family members and that too mostly blood relatives (son/daughter). For folks without kids old age is going to be hell with no support during critical condition. Govt and private services can only provide to some extent as they have to cater to thousands of other customers. With the breakdown of joint family network seniors are going to get hit the most. I am working on a solution how to fend it off for myself/spouse.
In US such support will cost a bomb, one reason for me to retire in India.
