Well, this is a can of worms...
Bjorn nailed it hard as regards the history. Bowwild has two very neat perspectives from which to draw and likely could quote liscense sales and hunter safety participation to demonstrate decline in new hunters.
As a professional educator teaching in the wildlife and resource field I see some of this from a different view.
My students are dedicated to what it is theu do. They do it differently then we do/did but they are doing it. I have several students that have spent the better part of this Illinois bow season doing grunt work for some local outfitters just to get some on ground experience in the hunting industry.
Most of them have watched the vids and laugh at them. They do not seem to be "sold" by all the hype on equipment and in fact several have asked me to help them get set up with trad stuff because they think its cool to hunt that way.
OK, now here is the educator thing.... We are dealing at the college entry level with Generation Y. They are a different kind of duck compared to the Baby Boomers (Bjorn, me Charlie Lamb, etc born post WWII) or generation X (born starting in the 60's) Generation Y are the true "Latch Key kids. Ed psychologists have found it very difficult to "breakdown" the identification of this group. They would just as soon send a text to someone standing next to them as talk. In fact, out side their closest peer group, they have very little conversation.
I guess its just "goes around come around." Those of us who are older will always think the younger group is "slacking" a bit.
