It seems to me that the younger folks are not really opposed to the idea of building a model, in fact, most I have known have tried it at least once. But, for many of the activities they have been involved in, they have, at the very least, received an award just for participating! No one wants to be responsible for telling a child that they didn't do very well, that might hurt their feelings and mess them up for life! And as all of us well know, model building takes a lot of time, and many failed attempts, to eventually become good at, the younger folks seem to get discouraged and give up on any activity that they don't look like an old pro at the first time they try it.
