Maybe not taking what we say at face value. Dentists, doctors or layers have been vastly used as a joke but of course it is an image and not necessarly pejorative. At least I don't use it that way. What it means is that we know MF manufacturers have big part of their buyers in the hobbyist, high-end amateur sphere, in oposition to the profesional. Without them they would probably not exist today.
It is so true that Hassy can release a Ferrari model, or whatever golden collector and of course the target is not the working pro.
Those "dentists" is an image that represent in a way the wealphy hobbyist, ok, with a sort of tease behind when we'd like them, or sometimes bark on them to improve on features really usefull for the pro.
That is at least the way I understand it as a non english lenguage native.
If my neighbour wants to buy a 55K back, I have not one objection neither it appears to me scandalous. Everybody is luckily free to spend their money where they want to. I would probably think in my mind that it is a whim. I also have mine, they are just different.
Then, if we take that, the whim, in a bigger context we hardly can avoid to make a correlation between the kidult and the global system itself that is showing signs of degeneration (to be polite), but that is another debate completly out of this forum.
