I'm a pro photographer. Leica does have their "ambassadors" like any other brand. However, most Leica users are upper class hobbyist photographers or artistic photographers. Leica's bread and butter come from their optics which is used in many applications (science, medical, etc) and of course, their name (example Panasonic cameras with Leica optics).
Many will pay $3000+ for a computer only to upgrade it in 3-4 years. People will pay $30k+ for a car and get 10-15 years out of it. The $7000 drum set (more with hardware and cymbals) can be a lifetime kit. Plus, years down the road, have a decent resale value. If playing drums are important enough in your life, that is not a bad long term purchase. Plus, there are many fine drum sets at all price points. Its all how you look at it.
