Social care
This sort of help is mostly done by families, and mostly by women.  In the past a lot was done by religious people.  Workhouses and hospitals were often full of people who needed social care and had nobody to look after them.  As medicine developed social care became more separate. Payment for health care is often different from payments for health care. There may be argument about who should pay.  Care for old people near the end of life  is very different from care for children and young people. Private insurance is not very successful. Not everyone needs social care and young people are reluctant to take out insurance. Germany and Japan have set up systems which try to balance society’s and a individual responsibilities.
