The time involved is basically the same for laborer, craftsman and artist; they differ only in quality of and intention behind the effort. The laborer could be a craftsman or an artist by changing his perspective and approach to his work. From this perspective, the laborer is lesser because he does not fully apply himself, not as a result of his profession.
There are a lot of ways to deconstruct a one dimensional artists > craftsmen > laborers point of view because it is overly simplistic.
If people are elitists at work and they're snooty about it, why stop them?
I would not want to stop people being elitist, only for those who are to understand that their behaviour has a cost on at least some of those around them.
