His most famous book, Time, Labor and Social Domination, is not the clearest writing to say the least, but really dumb basic idea is that the downside of work during capitalism are less "boss mean" than the rat race / treadmill of more hours, more deadlines etc.
Whatever you say about the Dwarf Fortress creators, one thing that is clear is that they hopped way the fuck off that treadmill. Money gave Notch a "rush" (pun very much intended!) but the Adam's brothers were clearly in no rush.
I think that means this success will not get to their heads. He who was never running won't trip.
