Everything you have said is true and well articulated.
However it is worth noting that this is handled differently within different cultures and even within different fields within one culture. For instance, my step-mother is originally from Korea and she tells me that elder generations are treated with much more respect than they tend to be in America.
In my own observations in America, I have seen a distinct preference for younger employees in fields such as technology. On the other hand, from what I have seen in law, medicine, and intelligence analysis age seems to be less of a factor and the older practitioneers seem to have some advantage in the fact that they have had more time to build seniority.
