This topic was covered very extensively about a year ago, but it never hurts to reexplore these issues every so often. It allows new members to contribute and see how everyone else feels about modeling issues.
*IMHO Alert*
Whether we're talking about stamps or coins, paintings or sculptures, memorabilia or model kits, pure collectors fill an important niche in society. Their love of a subject and it's proper care and storage, ensures that items will remain in pristine condition for generations of people to view, purchase, or just appreciate. From a modeler's perspective, pure collecters are seen as both a bane and a benefit - depending on the point of view.
Many modeler's believe that every kit manufactured should be built...period. While this is an understandable viewpoint, wouldn't it be sad if there were absolutely NO model kits still in existence from the 1940's, 1950's, or 1960's? No way to see how the kits were packaged, how the instructions looked, or the condition of the parts? If not for collectors who care for these rare and important historical aspects of our hobby, we would have far less knowledge about our hobby's past and couldn't appreciate these beautiful old kits.
However, there is another "gremlin" that has creapt into our hobby and it's NOT a collector. Many of these individuals may call themselves collectors and even modelers may consider them collectors, but they're not. These people are model kit "investors". Investors have NO particular love for model kits or their history and are really NOT looking to preserve a model kit for 30 or 40 years. They are buying up mass quantities of model kits strickly on the speculation that the kits will become more valuable one, two, or three years down the road. They will then attempt to resell the kits at incredible prices and make a hefty profit. These are the people who really hurt the modeling industry and adversely affect the wallet of the average model builder.
