As I'm 18 years old I think I can give a good perspective on this...
First of, many of the points who are pointed out by some of you guys are completly right,
The price of modelling has become higher than ever, but allowance has risen to,
I get about 20 euros a week, which is pretty common, even a bit on the higher side,
as you all know, you could allready buy yourself something decent with that, so the price? hmmm, maybe, it could be a factor, but I think the main reasons are that,
Back in the day, you bought yourself a normal kit, which contains something about 20 parts,
If you buy a normal kit today, you allready get a kit with a whopping 80 parts or more, and most kids want something big, which is often not good because it also makes it harder to complete it, and never hits the finish line, so he will never ask for a second kit, and never discover what a great hobby this is, I was lucky, bought myself a C-47 from revell, a BIG kit, who doesn't contain that many parts and fits together OKAY.
In my eyes, the biggest factor is, there are to many, easier options to go with,
when you go to a toy store, a child can't choose what he wants, because there are to many things to choose from, and lots of parents think of modelling as a dull, maybe even stupid hobby to have
(offcourse we would disagree, but we aren't the common people to, and we know what modelling holds inside) so when the kids points to a box saying, I want that, the parent will go, but don't you want some lego's or playmobil?
When you shuv a Playstation 3 (game) under a kids nose with a model kit next to it, 90% of the kids will choose the playstation 3, xbox 360 or whatever...
But what should also be known is that, the hobby isn't dying, it's changing.
I know lots of kids who model, but they don't build planes, tanks or boats, or actualy they do, but they build Warhammer, lord of the rings, star wars planes, tanks ,boats or whatever it contains, in which they can play boardgames with.
And there are kids who build models, but most of them stay hiding in the shadows, I know my LHS-keeper very well, he tells me that it's true that I am the only one of my age (14 - 25) that builds models, but there are kids who do build models, he has about 5-8 kids from around 6-12 that get there mom to the store to buy a kit, so it's no so bad as we often think it is, but if we keep on buying kits in expo's, internet and various, which makes our LHS dissappaer, then modelling is doomed to fade away at some point...
But I don't think that is how it will end, even if it will end, look at all these brands who make so much new kits that we have to many options on buying the same plane but from three or four different manufacterers,
you can't say the hobby is dying, but it is true that, modelling isn't as popular as it used to be,
but main reason is, there are to many things to do, with not enough time to try even half of 'em.
I just think, that instead of dying, the age group has changed, and we can't even say what the modelling society looks like in country's as Japan, Korea and China. Because from some pictures I have seen on the internet,
I just think that the largest modelling society, can be found over there. Especially in the first two examples.
