As I am approaching the retirement age, I don't see this happening. I actually can't even imagine education expiring somehow or marketable skills needing "retooling". But even if these scenarios all happened, you are basically advocating that somebody still have to provide highly paying job for you even though you don't have an education or skill and there are plenty of people who are higher skilled than you? Would you hire somebody like that to do work on your house or, perhaps, you'd like to receive medical treatment from a doctor like that? If not, why others should hire you?
