No actually, it is very easy to understand. Here is a 3-step guide that for everyone!
1. People accumulate money. Often this excess of money comes in retirement.
2. They buy the most (recognizably) expensive camera they can. Leica.
3. Now they justify the 200%+ premium over other camera brands by posting endlessly about the 'mystique' and how awesome Leicas are. Meanwhile, their photos are still sub-par. The more they spent on the camera, the more time they spend online talking about their cameras, and the less time they spend shooting or in the darkroom.
