Well, suppose a miraculous breakthrough occurred and the life expectancy shot from, say, 75 years up to 750, pushing back the onset of debilitating age.

Surely it would seem like grumbling to dismiss it as: "Now they can keep you alive long enough to squeeze out an extra 675 years at your desk."

This might be rather millenial of me, but I don't view retirement as some long-deferred tasty dessert for being a good compliant worker who eats their vegetables... as much as a someday-unavoidable lifestyle transition.
