Great Question! (Prof. emeritus Hans Abbing, Rotterdam University/2002/Amsterdam University Press)


 
table 3 explanations for why incomes are low in the arts: (page 113)

1 The winner-takes-all principle: Winner-takes-all markets are important in the arts. They attract many competitors. 

2 Unfitness for non-arts professions: Because artists believe they are unfit for other, non-art professions, they believe they are better off in the arts despite the prospect of a low income. 

3 An orientation towards non-monetary rewards: (a) The average artist is more interested in non-monetary rewards than other professionals, while (b) such rewards are (thought to be) available in abundance in the arts. 

4 An inclination to take risks: (a) the average artist is less risk-aversive than other professionals, while (b) high stakes, in the form of both non-monetary and monetary income, are (thought to be) available in abundance in the arts. 

5 Overconfidence and self-deceit: more than other professionals, the average artist is inclined to overestimate his or her skills and luck and at the same time, ignore available information; therefore they overestimate the rewards available to them in the arts. 

6 Wrong information: the average artist is less well informed than other professionals; therefore they overestimate the rewards available to them in the arts.
