I'm in the UK rather than the US so there might be a cultural difference I've no exposure to, but the following is my anecdotal take: I've had a lot of experience working in different companies and find that competence, intelligence and hard work are distributed evenly WRT age; that is to say there is no correlation. When I hear complaints like this I tend to ask myself "is this a staff problem or a management failure?" And most of the time, IME it's the latter.
