Only an IT issue?
I know this is an IT oriented website but I don't see how this only a problem for IT jobs? Does HR, when trying to fill a position of any relevance, really want someone with only 10 or less years of time left?
The only exception I see is in management positions, where experience is a requirement. And, for the most part, these jobs don't require creative work using tools and technology, just managing people and doing budgets. You can be 90 and do that.
I'm sure that offends quite a few people in management ranks who don't feel they are the Pointy Haired Boss in Dilbert. But as the Peter Principle talked about many years ago, that is where people try to go as they age. For evidence, why do so many upper management positions get filled by people who were let go from those positions at another company? Because you are most qualified if you have done it before, age is irrelevant. Let's face it, has the art of managing people and doing budgets really changed in 30 years? 40 years?
