Throughout history, people have struggled with the question of how they will support themselves in their old age. For the ancient Greeks, it came down to stockpiling jars of olive oil. In the Middle Ages, the feudal system saw the rise of the concept of charity. And, of course, families and relatives felt some responsibility for caring for aged parents. But, as society grew in size and complexity, the family was no longer capable of providing for its elderly members. This lead to the creation of guilds and "Friendly Societies" in England during the 16th Century. Members contributed a portion of their income every year that they worked, and in return were assured of care in their later years.
