Research has demonstrated that people who view their craft as a calling, take pride in it and view it as an important duty in society (even if it is menial) are happier and healthier. I remember watching an interview with a migrant farm worker who took pride in the speed and quality of his berry picking, and the fact that he could pick with two hands simultaneously. That was such an inspiring example for me.
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.
