Interesting and very complicated topic. I was reading a thread about what items kids don't want to inherit from their parents. These included furnature, pianos, china, sterling silver flatware, pictures, etc. This loosely mirrors what people collect. There will always be a tiny percentage of people who collect artwork, paintings, watches, old cars, motorcycles, fountain pens, you name it. Speaking from personal experience my 11 year old son isn't the least bit interested in my hobbies. Gun collecting, watches, motorcycles, old cars, fraternal organizations...No interest whatsoever!!! Go to a local car show sometime. Nothing but old people (like me!!!) arriving with their cars. Are the older people the only ones that can afford them, or maybe younger people don't want to mess with the expense of servicing and storage??? I don't know. Motorcycles??? Forget it. Harley is in serious trouble. The average age of a Harley owner is 60+. Younger people just aren't getting licenses. Watches?? I have a large network of people I know through Church, Lodge, work, sports, etc. I can count the number of people on one hand that are into watches. Again, I know there are people who collect super high end cars, watches, homes, boats, firearms.....But if any hobby is to continue, it needs an influx of new younger people.
