Building on that, instead of viewing retirement (age) from a cost perspective (i.e. we have x budget and y lifespan, hence retirement age is z), it would be refreshing to see a high-quality and long retirement as starting point, and then figure out how to organize for that. One way would be to reduce burden on services indeed. A low retirement age (for those who want it) is a sign of a wealthy nation and something to strive for.
