I use dedicated haulers too.
I'm sure if they had their way though they'd stop hauling, build a crafts workshop in the mines, and churn out stone mugs. And when that got cluttered they'd move over a ways into more stone and build a new workshop. Anything that puts money in your account, right?
Dwarves who are starving should wait by the stockpile for someone carrying something valuable to come by, knock him over, pick the thing up, and haul it the remaining few tiles.
Heck, Dwarves should mug each other. Steal from the stockpiles. Frame the Hammerer so he can be deposed. At least, start choosing the hauling tasks that are worth the most pay. And outright refuse to haul a stone from the bottom level up to the mason shop.
Then again, I think the Dwarves are probably pretty deluded to stand for the nobles at all. Once a 7-dwarf expedition gets entrenched not even the mightiest dwarven seige could take them out. The King should be a totally nominal figure.
I'm just thinking about how, if placed in the same setting with all the same rules, any of us would work to survive and prosper.
Oh, and a measure of dictatorship is present in the DF economy - there is still an overseer (you) deciding who gets to do what jobs. A dwarf peasant can't come in and just build a craft shop in the basement mines. If you tell him to haul, he just has to go haul.
He walks up with the other immigrants and gets his orders, and becomes crestfallen when he realizes he left the Mountainhomes to come here for this. Slow starvation among opulence. Sleeping in a rough stone corner while rhino lizards eat your toes and a moronic Baron's kid walks by with strands of ☼Quarry Bush Leaves Roast☼ dangling from his insipid jowls. Dreading the moments when you'll be sent to the surface after a seige to pick up Narrow Giant Cave Spider Silk Loincloths, hoping there isn't a goblin murderer hiding behind a rock waiting to throttle you.
I think the new expedition is not actually a bunch of Dwarves who have investors: it's seven haulers who managed to escape with their lives and about ☼3,000 in items stolen from the stockpiles. They immediately institute communism but as soon as they hit Legendary they forget what it was like and are completely corrupted by wealth. Then seven of their haulers escape ...
The King is a warlord who wanders from fortress to fortress installing his cousins and sycophants as brutal nobles. When their inevitable mismanagement and negligence causes a tantrum spiral and ruin, it doesn't matter to him. He's already seen all the lovely blue stuff get mined out and has moved on to the next fort. His entire form of government is based on the decadence of his incompetent lackeys and the oppression of the peasants.
