My understanding is that part of this panic is due to how society is structured somewhat as a pyramid scheme. Social benefits to retirees are expected to come from the economic productivity of a younger working class. Large businesses which are designed to make high-level execs wealthy at the expense of their lowest-level employees require a steady stream of fresh meat. I think some of the economic changes we're seeing is related to declining fertility rates.
