Future of the classic car hobby may be unstable per experts?

Been following this thread with great interest. So may good observations. I'm 64 and was SO fortunate to be there in the day. The only thing I would like to add is that yes, the hobby may be off its highs but I feel by only a small margin. Could just be the state of the economy. On the up side one needs to a look at the after market business such as Year One and others that are apparently doing well and are always adding new line items and expanding their catalogs. I would think they have done their home work and understand trends better than anyone.
Another barometer of the hobby I like to follow is the Mecum auctions. Yes, Dana is unique, but his auctions are more real world than others, has a good sell % and has a broad buyer base. As a bonus he also expose many of the curious to the muscle car experience.
Just my .02.
