No, it's not too late. The hidden part of the policy is that you simply euthanize those too old and sick to work. That's also the hidden part of ObamaCare.
Look, I know this is counterintuitive, but 1/1, 1/2, 1/4, and so on and so on. Euthanasia doesn’t solve the problem of each generation being half the size of the previous generation. You’d have half the workers you had previous. Even if you killed everyone at 65, you still will have a worker shortage.
