Actually the pilots case is instructive, in that the competency and their safety were tested on a regular basis. They absolutely guarantee that every pilot who's flying the plane is safe and competent to fly that plane. That's a very good example of the kind of workplace testing that is possible. They test all the pilots the same way. To distinguish on the basis of age instead of actual competence I think is wrong. There's no need for it.
While the chamber is right to worry about safety concerns, there are ways of dealing with that without using age as the criteria.
