Wow - some interesting points here....... Where are we headed??? The collectors are running the show IMHO..... It's whatever any and all manufacturers can sell to make that "bottom line" stay well in the black...
The gold card holders are there - yes, and that does seem to make the days of the kits numbered, or at least, shrinking... but there are still people out there that simply can't leave anything alone

they have to create things, (Weather, detail etc.)
In all walks of life, there is nothing that compaires to the "overall" scope of this hobby... You can buy a boat, you can buy a bike, or a car.. and keep using them as dual purpose (family or single hobby) but you can't take someone in (on) a train ride on your layout.
That's where it falls apart.... I could always get someone into the antique car and i could always give them the first hand inpressions of driving it and "the energy involved" but people grow up and change and as has been said -- need money for other things (Kids, houses etc) but if you are interested in railroading, there's always model railroading... The kids come in and see the layouts the older folks build, then they go to cars & girls and family, then come back.... How do i know this?? Because I did exactly that

I was into trains until i was in junior high school.... (Homework, model cars) then high school (real Cars, Girls and homework) then real work.. then finally got back into modeling at the age of 26, now I'm 47 and have never regretted a second of it
The detailing, modeling, operating, and "Watching them run" are all different stages and levels of model railroading... everyone has to find their comfort level... but the 3 things you really need are time, money and an imagination..... Something video games have taken a huge chunk out of.....
You can use real world things to ride in and build models of them... but there are very few who will just buy a railroad layout R-T-R and then not get hooked in to some manner of building.... Another aspect is, that you have to be an electrician, a woodcrafter and have a lot of patience.... something that definatly comes with experience and getting older (30??? as compaired to 18)

Oh... and dedication to the hobby helps too
