By some measures, the nobles, who own everything, should be included in the same lot as "legendaries", since they are effectively the CEOs or major shareholders of Dwarf Fortress - they do no real work, make random insane demands, and live a life of luxury simply because they were born owning everything. (We all just hate nobles because we're playing from the perspective of the communist dwarves... damn capitalists!)
I see the nobles as being a lot more like the looters (antagonists from Atlas Shrugged), which include people who owned businesses but didn't know how to do anything, and made insane demands without caring about possibility.
Yes, but what I was saying was that while we can easily perceive nobles in DF that way, in reality, it's not that easy to see who is a looter, and who is a ruthless and successful capitalist.
The book "Outliers" is pretty much all about this, but I think one quote in particular illustrates the idea, where Jeb Bush was talking about how he was an "entirely self-made man", and that his family's huge wealth and political influence (which, after all, helped him become governor), as well as the education and job opportunities that they afforded, as well as the friends and contacts he could make by leveraging those assets, were actually a
detriment to his personal success.
I just imagine the nobles being sort of like this - convinced that they got where they are thanks to their own hard work, instead of being lazy, useless, and overall generally detrimental to the function of the fortress they are leeching off of, thanks only to their accident of birth.
This brings up the problem of just who the "skilled" people are - I mean, really, is a skilled soapmaker a "skilled" dwarf? It doesn't even make them a better worker when you get right down to it...
The notion of the looters and such was that they were, basically, the people who gamed the system, who lived on welfare... But even peasants are actually relatively hard-working haulers. It's simply that hauling doesn't give experience. If it did, they would be high-level haulers who got paid fairly well. The idea of Atlus Shrugged was that the "skilled" were metaphorically carrying the weight of the world on their shoulders, supporting the rest of society, which was decadant and leeched off the work of a few... but the reason you have haulers is that without haulers, the legendaries have to haul their own crap, and the division of labor (if unfair) actually helps carry the weight of dwarven society. The unskilled are generally as productive as the skilled, they simply either haven't had a chance to get their XP up, or have been stuck with hauling duty.
(Unless you want to divide your fort by their "excellence" trait, which says whether they just do enough work to get by, or are continually striving for excellence.)
Really, the only leeches are the nobles and children... which again, wind up just being references to the "Unfortunate Accident" article... unless, of course, you want to give your female dwarves in the military a fine suit of babymail armor. (And even those tend to make decent harvesters... and with a large enough farm, and a textile mill or kitchen for export, you can actually really use that.)
