If that doesn’t work then try 80 to 95, then shucks 60 to 70, and when the kids get in charge 30 might seem reasonable.
Who knows at this point? What I think is clear is that as a nation it looks like we are getting to the point where we have to choose between remaining as a world superpower and supporting science and research or being the caretaker of all the nation’s elderly, because doing all this at once will simply be completely impossible. I think anyone who thinks the US will ever be able to afford to police the world and be responsible for taking care of all our old people is living on a completely different plane of reality.
