We are already in a world in which people in their late fifties or older can do little productive work because they must care for an elderly parent. The economic costs of these realities can be staggering when we consider their spread and magnitude. One aged person contributes nothing; another person, of necessity able-bodied, is occupied by little more than the care of the first; and a third person is physically tied down and left with little time and space for productive work. The older a person gets, the more expensive it becomes to keep alive.
