The Government could make retirement illegal altogether, and the problem would be solved.
They don’t even have to “make” retirement illegal, sometimes it takes care of itself. There are a LOT of people in their 70s and 80s who are working today and not by choice, since their gold-plated pension fund went belly up along with the company back in the 80s. I suppose that was a portent of things to come on a smaller scale.
The difference now is a HUGH demographic of “baby boomers” who will probably overwhelm the system just as they did for everything else.
