Why are bandits in forts, why are bandits in caves, why are bandits standing by the road? You could ask that about anything really. Does there have to be a reason for everything? Who knows in that world why anything really happens other than the people writing the story? It doesn't always have to make perfect sense to us.
Really, I wasn't asking why they existed. I was asking why they were doing hard work. Grab a pickaxe and start pounding on the side of a mountain. You'll understand really quick. Just seems illogical that someone would embark on a life of crime, just to be a coal miner.
And, yeah, there has to be a reason for everything, and yeah, it does have to make sense
