It is not about old people, they don't want this either. If anything old people are a lot more conservative and libertarian. Once you are 82 you sure made piece with dying after all most people you grew up with have long passed.

It is more about catering to the sort of voter that is easily scared, exposed for the first time to the fact that life is indeed fragile and limited, a voter that looks at someone to protect them.

Old people are the pawns and "protecting" them is the spectacle of demonstrating competence in governing.
