I like KD Burke's point here.

The artist who creates in pursuit of becoming a master and for no other reason is noble in the fact that they are only answerable to themselves... they have no REAL outside pressures on their creation if they don't want it. If they choose to subject their creation to review, then that is a pressure they add themselves.

Those who create for a marketplace are put under additional pressures of price / quality scrutiny. They create their own external pressure.

The problem with this model is that the first person may become a master, but must have another source of income to sustain him/herself as hobbies for hobbies sake won't pay the bills. Those who CHOOSE to do it for a living are under pressure, by their own design. As it is their own decision, do they really have a reason to complain about wages / income? Did they not understand the realities of capitalist market before hanging out their shingle?
