Mike,
That's a very valid point. Younger collectors have said to me, that they feel the experienced, veteran collectors are unaproachable and they receive cool receptions. Opinions vary, though I do believe there is some merit in the statement. Fostering an interest in the hobby will help ensure that when the time comes, older collectors don't get totally hosed. Those who will be holding onto their stuff for another 30 years...we'll have to see.
** A concern is this: if in the near future items are manufactured to such a degree that it will be difficult to differentiate between good and bad, it could potentially turn interested persons away, simply because they won't take the risk. I personally see this as a possible and significant risk in the future.
