I've heard through various sources that the 'old person' problem is getting worse. In dysfunctional bureaucracies, people are going past 70, even if they don't really work any more. To get rid of them, you must 'show cause' and give a huge severance for years of service. Naturally, this can't be done, since nobody really works in those places, and anything you do will be 'age discrimination'.
I retired early, but I can understand some people who have blown all their money and have nothing else to do. Still, politically, and to make room for young people, they should start chopping severance every year after 65.
I can't wait to hear stories of the 'World's oldest employee'. They should get to be a hundred, at least. There will be a statement from the company saying that Stan has been a fine programmer. Really, what else could they do?
