I think Dan was pretty on topic there.
Modelbuilding is a hobby. One that requires disposable income. It comes down to the haves and have nots. Either you have dsiposable income or you don't. Its not a class thing its a priority thing. How important is it to you?
If you have x amount of dollars to spend on something you pick and choose what you will spend that money on. Cigarettes, soda, a movie, video game, concert tickets, model, paint etc. This is disposable income, outside of rent, groceries, utilities, bills etc.
Several threads over the last couple of years have bemoaned and lamented the price of the hobby vs. entertainment value, other topics included folks lamenting that they couldn't afford a particular kit, (some ironicly could afford several cheaper kits that if added together would have equaled the big money kit) but they chose to spread their money out feeling that the larger $ vs. entertainment was better spent buying 3, 1/72 kits as opposed to 1, 1/35. It was what they perceived as their threshold of expenditure.
So, to get back to Dan's post. If the costs associated with this hobby go up, to the point that those with more disposabe income will get first pick at the choicest morcels and aftermarket stuff, that is economics. I would like to drive a BMW, I can't afford one, should BMW make a economy version so I can afford it? No. I will settle for less or what I can afford. So just as in the BMW, so will participants in the hobby cope with rising costs. They may not be able to afford the higerpriced kits or the aftermarket doo dads to pimp out their kit, but what they will do is buy the cheaper or less expensive kits and put a little more work into them to "pimp" them out as well as do more scratchbuilding to fill in the gaps where they would use the AM if the money was available. That to me make them better modelers than the guys who can throw a seemingly endless amount of money at something and are still limited by ability. i.e. look at the super detail tiger from a while back. As impressive as it was for detail and amount spent on it, frankly I was not impressed because it was just aftermarket brass, resin, putty and styrene. No tank jumped out at me, I was not impressed with the weathering that wasn't there.
Even if the mfr,'s price the kits so far out of reach that only a few will ever be able to afford them, I think you'll find that those really interested in model building and making madels (as opposed to assembling) will find ways around the financial obstacles placed before them. This can mean making do with poorer quality kits or scratchbuilding from less expensive materials what they want to upgrade the kit. A really good example of this can be pulledf rom history. Captured Bristish and French Sailors during the Napoleonic Wars would make absolutely beautiful ship models from bits of rags, soup bones, wood they could scavenge and thread to sell to such distinguished clientele as admirality boards, Captains, Admirals and Gentry, to subsidize their stays in the prisons. This got htem extra food, clothing or to pay their way out. They made do.
I hate to think that we as creative artists in this hobby are so reliant on aftermarket and commercial kits that we have forgotten what it was about to be intuitive, imaginative, creative and resourceful in our endeavors.
